Manifolds Diaphragm and Bellows Valve
DRASTAR Core Valve is an advanced concept of valve that Drastar developed for ultra-high purity specialty gases extensively used in the semiconductor manufacturing line, bulk gas line and other facility lines. Core valves have integrated and improved all the merits of diaphragm valve, bellows valve and needle valve to best work (Drastar Patent #10-1510987). ◈ Surface finishes to AP or B.A. 25Ra E.P. 10Ra or 5Ra ◈ Improved for micro and precise adjustment ◈ Pull and lock device (Drastar’s patent #10-1370537) prevents the knob’s self-turning ◈ Easy operation ◈ Applicable for 20bar(290psig) ~ max 750bar(11,000psig) With DRASTAR’s patented (patent #10-1370537) “ push and lock type handle ”, you can operate it easily and stably; “locking” by pushing down the handle will prevent any slight change of pre-set pressure value, which could possibly be caused by any vibration from gas pipeline or ambient applications and the other way “unlocking” by pulling it back enables you to adjust the pressure value freely again. |
