空圧式ピンチバルブ
空圧式ピンチバルブは補強エラストマースリーブの周囲のバルブボディに圧縮空気を送り込んで閉止・調整するため、流体はスリーブのみに接触し、操作は完全に空圧です。摩耗性スラリー・粉体・腐食性液体へのフルボアon/offと比例供給用途に対応します。範囲は4シリーズ—VMPプラスチックボディ3/8"～2"（10～50mm）、VMCアルミ/ステンレスボディ3/8"～4"（10～100mm）、ANSIまたはDINフランジのVF、サイロ排出用VT—で、スリーブ材料は用途に合わせて選定（摩耗性スラリーは天然ゴム、薬品耐性はEPDM、油含有流体はNBR、衛生用途はFDA適合材）、空気圧による正確な流量調整、気泡レベルの締切、性能影響なしの水平・垂直据付に対応します。選定は管径と接続方式、媒体に対するスリーブ材、管圧に抗して閉じるための圧縮空気供給量がポイントです。

| vacuum capability | usable at vacuum pressures down to around 100 mbar without auxiliary equipment |
| operating temp limits | down to -10°C without additional measures; maximum sleeve temperature +130°C (silicone) or +120°C (FPM) |
| enclosed double acting air pressure | the enclosed-body double-acting pneumatic execution requires 5-6 bar of control air pressure to open and close, in both single-cylinder and twin-cylinder builds |
| double acting cylinder size split | single-cylinder builds: 15 mm to 50 mm, twin-cylinder builds: 65 mm to 250 mm |

| pneumatic valve accessories | pneumatic valve accessories: solenoid valve, pressure regulators and limit switches |
| double acting cylinder principle | the valve is pneumatically operated with one or two pneumatic cylinders in a double-acting arrangement |
| fail safe air to open design | normally-closed fail-safe execution: air to open, spring return - air pressure opens the valve and removing the air closes it to the fail-safe position, while the open valve allows full unobstructed flow |
| nc opening pressure by cylinder | single-cylinder builds require 3-4 bar to open; twin-cylinder builds require 5.5-6 bar to open |
| nc max line pressure by size | 15 mm - 32 mm: maximum line pressure 5 bar, 40 mm - 150 mm: maximum line pressure 3 bar, 200 mm: maximum line pressure 2 bar, 250 mm: maximum line pressure 2 bar |
| nc sleeve compounds | normally-closed execution sleeve compounds: natural rubber (standard), EPDM food quality, EPDM and neoprene |
| nc accessories with positioner | normally-closed execution accessories: solenoid valve, pressure regulators and limit switches, plus an electro-pneumatic positioner |
| built in actuator design | the valve body acts as a built-in actuator, eliminating costly hydraulic, pneumatic or electric operators; actuation is accomplished by air or hydraulic pressure placed directly on the elastomer sleeve |
| drop tight closure entrapped solids | the elastomer sleeve is the valve only wetted part, and its rugged flexibility allows the valve to close drop tight around entrapped solids |
| general closure differential rule | in general, 25 psi over line pressure is required for full closure of air actuated pinch valves |
| air actuated product lines | air-actuated Type A, all-rubber air-actuated Type R, air-actuated Series 2600 compact line, air-actuated Series 4700 lightweight line |
| pneumatic envelope din40 300 | pneumatic pinch valve in a durable aluminium body, sizes DN40 to DN300 (1-1/2 to 12 inch), working pressure 2-6 bar for efficient and safe flow regulation, with flanged ends for easy installation |
| socket sleeve temp build | aluminium sockets with steel bushing; sleeve in natural rubber or EPDM; sealing grade per ANSI B16.104 leakage class; working temperature -20°C to +150°C |
| pneumatic accessory program | solenoid valve, pressure switch, pressure regulator, safety protection device, filter, vacuum assembly, proportional regulating valve |
| oval shell air saving lip | the shells of all flanged pinch valves are flat and oval, ensuring low compressed air consumption and guaranteeing the predetermined lip bending direction for 100% shut-off of the medium flow even when large solid particles cover the inner bushing |
| sleeve sole medium contact | the pinch valve features three main components - sleeve, body and actuator - and the sleeve is the only part in contact with the process medium; the materials of all three components can be selected to suit process conditions |
| dn80 pn10 sample envelope | sample pneumatic build: aluminium alloy body, DN80 (80 mm, 3 inch), PN10 rating, RF flanged ends, temperature range -35°C to +130°C, operated on compressed air or fluid |
| reopen on exhaust elasticity | closing relies on compressed air or fluid injected directly into the valve body with a minimum differential pressure of 2 bar, forcing the reinforced rubber sleeve to collapse inward into the same elliptical lip shape; when the air pressure is exhausted the sleeve natural elasticity pops it back open to a full-bore circular state |
| body material and diameter options | body material options: aluminium alloy or stainless steel; nominal diameter DN40-DN300 |
