PN25 BS5163 Non Rising Resilient Gate Valves DN50 - DN300

PN25 BS5163 Non Rising Resilient Seated Gate Valves DN50-DN300

BS5163 Non-rising Stem Resilient Seated Gate Valve Gland Type

1. PRODUCT PROFILE

BS5163 Non-rising Stem Resilient Seated Gate Valve has many advantages against old fashioned metal seated gate valve. Lack of valve pocket for gate seat maintains smooth and unobstructed waterway; eliminates depositing of impurities which may cause ineffective shut-off and leaking from metal to metal contact in time. Resilient seat contact is easily and  perfectly maintained and this allows quick and perfect change of wedge without dismantling the valve from pipeline when the
rubber lining is worn out. In turn, when the metal-seated gate valve leaks, it should be returned to its factory for renewing and precise machining of metal seats, or it should be thrown away.

2. FEATURES

· Full bore design

· Rolled stem ensure smooth thread edges and double thread

· The valve plate adopts high-quality overall rubber coating, the use of advanced technology makes the vulcanized rubber vulcanization after the valve plate to ensure accurate geometry, and the rubber and ductile iron gate connection is firm and not easy to fall off with good elastic memory, so as to ensure the stable performance of the valve sealing.

· Low operating torque

· Good and clear body marking

· Online replaceable under full pressure with valve fully opened; Three o-rings protects upper stem from impurities entering from the water way

· Every valve be 100% tested and qualified before packmaterialing and delivery
