공압 핀치 밸브
공압 핀치 밸브는 보강 엘라스토머 슬리브 주위 바디로 압축 공기를 유입해 닫거나 조절하므로, 유체는 슬리브에만 닿고 조작은 완전 공압입니다 — 연마성 슬러리, 분말, 부식성 유체의 풀 보어 온/오프 및 비례 투약 임무입니다. 범위는 네 개의 라인입니다 — 3/8"-2"(10-50 mm)의 VMP 플라스틱 바디, 3/8"-4"(10-100 mm)의 VMC 알루미늄 및 스테인리스 바디, ANSI 또는 DIN 플랜지 접속의 VF, 사일로 언로딩용 VT — 슬리브 컴파운드는 임무에 맞춰 선택합니다(연마성 슬러리용 천연고무, 내화학용 EPDM, 함유 오일용 NBR, 위생용 FDA 부합 재료). 공기 압력을 통한 정밀 퍼센트 유량 조절, 버블타이트 차단, 성능 영향 없는 수평/수직 설치가 제공됩니다. 선정은 관 사이즈 및 접속 형식, 유체에 대한 슬리브 컴파운드, 관내 압력에 대항해 닫는 데 필요한 압축 공기 공급에 따라 결정됩니다.

| 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 |

| 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 |

| 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 |
