Back Purging Fast Open/Close Angle Valve

As a specially designed valve applied in coal-prossed chemical facilities, the Back Purging Fast Open/Close Angle Valve installed on the top of S-1501. This equipment has high requirements on its open/close speed (within 0.25S for a circle), leakage class (ANSI VI, Buble Class), high operation pressure (medium as high pressure Nigitron, 5.6MPa—5.8 MPa) and high action frequency (1 circle per 15 mins). Our self-developed Back Purging Fast Open/Close Angle Valve has applied for national-patent. A special quenched hard alloy is used on plug and seat to guarantee the hardness of valve parts to meed the requirement of anti-erosion, anti-impact, high pressure difference resistant and high sealing ability. Based on its superior performance, our Back Purging Fast Open/Close Angle Valve is your perfect solution to replace imported expensive products.
