Product Description

PNEUMATIC PINCH VALVE GJ641X-10L
 

1. Main of components:

   Body, sleeve, Stem, pinch rod, side guide rod, Hand wheel etc.

1. Working principle:

when rotate the handle clockwise, valve stem drive the splint and compress sleeving to close valve, conversely, open the valve. So splint under the pull rod upper and downer to complete the work, because of the rubber sleeve can not sustain heavy strength, so when close it, operator feel a little collide is be ok, forbid to use other tools;
This valve can install on the pipe for free, no fluent direction limit, long term usage, if there is abrasion or leaks, just to remove the valve to replace a new valve core, the valve can use for a long time for economical and practical.

1. Installation and maintenance:

1. Could install it in any part of pipe and don't limit of the medium flow direction.
2. Low maintenance cost, don't need change the seat of valve, sealing material etc, only need change the rubber of sleeving.

1. Functions of Manual Pinch Valves and advantages:

1. Pinch valves can be used for On/Off, as well as throttling services
2. Pinch valves are ideal for on/off services because of their straight through design that allows for uninhibited flow
3. Straight through designs also have very little pressure drop between the inlet and outlet.
4. The effective throttling range of a pinch valve is usually between 10% and 95% of the rated flow capacity
5. Low maintenance
6. Low weight and easy operation
7. Easy changing the rubber sleeving and don't need stock other parts except the rubber sleeving.
