The Rhinoflex ‘P-Series’ air actuated pinch valves are simple, versatile and extremely cost effective pinch valves for all On-Off and Control applications. The rubber sleeve is the only wetted part and is housed in a solid ductile iron body. The gap between the sleeve and the inner wall of the body, acts as a built-in actuator and, when compressed air or hydraulic pressure is used, it ‘pinches’ the sleeve, eliminating the need for expensive pneumatic/hydraulic cylinders or electric actuators.
The sealing area of the pinch valve, is along the length of the sleeve, and will close ‘drop tight’, even on suspended particles. The sleeve will not cake up, as it is self-cleaning, every time the valve operates. The valve has no seats or packing and therefore no ‘Dead Zones’ to collect debris, which hampers valve function.
The Rhinoflex ‘P-Series’ pinch valve, is full bore, full flow, bi-directional, which can be used in any environment, and is a two-piece valve (body and sleeve). It does not have any moving parts that can malfunction, jam or fail. The operation of this valve will need about 2 Bar of differential pressure, and the valves are rated to 10 Bar max working pressure.
A volume booster or proportional relay is used to ‘Throttle/Control’ the flow if required. Various sleeve-trims like double wall, and conical orifice are used to acquire a variety of flow results, and the wear resistant capacity of the sleeves, will ensure trouble free maximum life. The sleeves are easily field replaceable, with the minimum of downtime required.
Typical applications of the Rhinoflex ‘P-Series’ pinch valves:
- Mining - Flotation Cells
- Steel - Iron Ore Reduction
- Pneumatic Conveying
- Bulk material transfer (silos)
- Abrasive powders and slurries
- Bottom Ash
- Chemical Handling
