패밀리 사양

Nominal valve connection size DN25 to DN150
Pressure class / nominal rating designation PN10, PN16, 150LB
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.
