| Sleeve Material | Rubber |
| Materials (component scope as published) | Cast iron, Carbon Steel, SS304, SS316 |
| Sleeve End Options | Extended hubs with clamps to slip over pipe ends, or flanged ends to standard dimensions |
| Enclosure Styles | Exposed-sleeve construction is standard; another style fully encloses the sleeve within a metallic body |
| Vacuum Limit | Exposed sleeves have limited vacuum duty (collapse tendency); encased builds can hold vacuum service by applying vacuum within the metal casing |
| Design standards | ANSI, DIN, JIS |
| Inspection and pressure-test standards | BS6755 |
| internals | Stem: Carbon Steel, Platen: Cast Iron, Trolley: Cast Iron, Bracket: Cast Iron, Handwheel: Cast Iron |
| flange dimension standards | ANSI B16.5, DIN3202, JIS |
| working principle | Full-bore (fully ported) control valve that obstructs flow by pinching an elastic sleeve |
| media isolation | Flowing media is completely isolated from any internal valve parts; the sleeve contains the media and reduces contamination |
| air operated self action | Air-operated builds need no actuator: the valve closes as soon as pressurized air enters the body and reopens by process-flow force when the air exhausts |
| construction | A sleeve molded of rubber or other synthetic material plus a pinching mechanism; all operating portions are external to the valve |
| abrasion resistance | Natural and synthetic rubber/plastic bodies give good abrasion resistance; little sleeve damage keeps flow virtually unimpeded |
| encased operation | Encased builds close by wheel-and-screw, hydraulic, or pneumatic pressure within the metal case forcing the sleeve walls together |
| generic envelope | General envelope: maximum operating temperature about 250 °F with pressure typically 100 psig at 1 in. falling to 15 psig at 12 in.; special builds span -100 to 550 °F at 300 psig |
| throttling character | Elastomer-sleeve construction gives smooth venturi flow, centerline closure and good throttling characteristics |
| sleeve selection rule | Sleeve material is selected on media corrosiveness/abrasiveness, with operation temperature kept within the polymer limit |
| execution options | Buried-service designs and options such as AWWA nuts, chainwheels, stem extensions and bevel gear actuators exist at reference executions |
| manual pressure size tiers | manual builds DN15-DN100 rated up to 5 bar, manual builds DN125-DN200 rated up to 3 bar, manual builds DN250 rated up to 2 bar, a DN80-only manual execution rated up to 6 bar, a high-pressure manual series to 400 mm at 1/6/10/16/25/40 bar pressure steps |
| manual pressure span 3 40 | manual pinch valve maximum operating pressure depends on the type and nominal size and spans 3 to 40 bar |
| manual handwheel pinch bar mechanism | manual builds close the sleeve with one or two pinch bars arranged horizontally above and below the sleeve, guided sideways by two rods and driven through a hand wheel |
| manual incrustation breakaway | closing-induced sleeve deformation causes incrustations inside the sleeve to break away, making the manual build practically blockage-free |
| air operating pressure rule | air-operated builds reach a maximum operating pressure of about 2-6 bar depending on the nominal diameter |
| air flanged series dn40 dn300 | air-operated flanged executions use a white epoxy powder coated aluminium body with PN10/16 flanges in sizes DN40-DN300 |
| air connection series spread | multi-connection air builds (flanges, tri-clamps, weld-on ends, threaded spigot, BSP internal thread) DN10-DN150, BSP internal-thread builds in standard black or white food-quality POM, DN10-DN50, socket-connection builds in stainless steel or POM with PVC or aluminium bodies, DN10-DN50, road-tanker semi-silo connection builds in DN80 and DN100 |
| high performance air series 400mm | a high-performance air-operated series extends to sizes up to 400 mm |
| sleeve compound options ako | natural rubber (standard and food quality), EPDM (standard and food quality), nitrile (standard and food quality), silicone, FKM, CSM, neoprene, butyl |
| air accessories list | solenoids, pressure switches, safety arrangements, vacuum systems, quick exhausts, proportional control, pressure regulators |
| elliptical body lip closure | the elliptical body design makes the rubber sleeve close the same way every time, forming a lip shape that gives completely tight shut-off even with large solids |
| air sleeve rebound reopen | when the compressed-air supply is interrupted and the casing vents, the sleeve reopens by its rebound elasticity, restoring full-bore passage |
| hd construction types | heavy-duty pinch valve series are offered in three construction types: open body, enclosed body, and enclosed/sealed body |
| hd size envelope by construction | open-body builds DN80-DN600 (3-24 in), enclosed builds DN25-DN1000 (1-40 in), enclosed/sealed builds DN25-DN800 (1-32 in) |
| hd pressure envelope by construction | pressure envelope 0-25 bar (0-362 psi) on open-body builds and 0-100 bar (0-1450 psi) on enclosed and enclosed/sealed builds |
| hd temp envelope by construction | temperature envelope -25 to +50 °C (-32 to 122 °F) on open-body builds and -25 to +80 °C (-32 to 176 °F) on enclosed and enclosed/sealed builds |
| two pinch bars centerline closure | during closing, two pinch bars squeeze the valve sleeve shut on the center line; in the open position the valve is full bore with no flow restrictions |
| bubble tight solids flaking | bubble-tight shut-off is maintained even with solids built up on the sleeve wall, and compression flakes crystallized particles off the sleeve surface |
| conical sleeve linear control | a conical sleeve improves controllability and produces a linear control curve |
| sleeve only contact replaceable | the sleeve is the only part in contact with the medium and the only replaceable part, changeable on site |
| control sizing iec60534 | control valve sizing for pinch valves is based on the international IEC 60534 standard, harmonized with ANSI/ISA S75 |
| gl size envelope by body | metal-body general-line builds DN50-DN250 (2-10 in), polyamide-blend plastic-body builds DN50-DN150 (2-6 in) |
| gl pressure envelope | both general-line series are rated 0-10 bar (0-145 psi) |
| gl temp envelope by body | metal-body general-line builds 0 to +110 °C (32-230 °F), polyamide-blend plastic-body builds 0 to +70 °C (32-158 °F) |
| gl face to face en558 | face-to-face dimensions follow industry standard EN 558 series 7, giving easy and quick installation |
| gl body opening tags | general-line metal-body builds carry opening tags in the sleeve as standard; the lighter plastic-body variant uses a corrosion-resistant polyamide-blend body |
| no stretch sleeve arches | one tube design uses two joint-like expansion arches that flex instead of stretch when closing, extending sleeve life |
| wear sensor indicator wire | an embedded wear-sensor indicator wire alerts maintenance personnel when the tube is worn, enabling preventive maintenance |
| inline tube change no recalibration | the tube or sleeve can be changed with the valve in line, saving maintenance time and eliminating the need for recalibration |
| self cleaning flexing antijam | the self-cleaning flexing action of the elastomer tube prevents build-up of scaling deposits and keeps the valve from seizing or jamming even with high solids |
| asme standard face to face | face-to-face dimensions to ASME standard allow drop-in placement into an existing pipeline replacing other standard valves |
| air flanged build listing sample | air-operated flanged builds are listed at DN80 (3 in) PN10 with RF flanged ends, in aluminium-alloy or stainless-steel bodies, including solenoid-integrated executions |
범위·출처 비고
| pressure framing | Pressure framing: the referenced general envelope is a sleeve rating (100 psig at 1 in. falling to 15 psig at 12 in., special builds 300 psig), while the tenant page lists flange classes PN10/PN16/150LB - sleeve pressure capacity and flange class are different limits and the mapping is unstated. |
|---|---|
| body concept | Body concept: general references describe the sleeve itself as the valve body (rubber/plastic bodies), while the tenant construction wraps a rubber sleeve in cast iron/carbon steel with cast-iron internals - the tenant build corresponds to the encased style, which references treat as a separate category. |
| duty split | Duty split: reference executions cite excellent throttling characteristics (venturi flow, centerline closure), while the tenant page positions the valve for isolation of abrasive/corrosive media - isolation and modulating duty depend on execution. |
| temperature ceiling | Temperature ceiling: the polymer limit governs operation temperature (about 250 °F general, to 550 °F special), but the tenant page states no temperature band for its rubber-sleeve build - the tenant ceiling depends on the sleeve polymer, which is listed only as generic rubber. |
