該塑料外殼帶有隔膜密封件、PPS 套管及 PPS 手輪。
隔膜是開關(guān)元件以及對外的密封元件，可簡單更換。
利用手輪可連續(xù)調(diào)整流量。
Manually-operated diaphragm valves in compact model consisting of plastic bodies,
 diaphragm seal, PPS bonnet and PPS handwheel.
 The diaphragm is both a switching element and a seal element towards the outside,
 and is easily replaced. The ? ow can be continually adjusted with the handwheel.
The valves have no dead volume and can be mounted to be self-draining.
