DIN-F4 Non-rising Stem Resilient Gate Valve Gland Type Square Cap PN10/16

1. PRODUCT PROFILE

DIN-F4 non-rising stem resilient gate valve gland type square cap is one type of gate valve with flexible wedge as its on-off disc, which moving direction is perpendicular with flow. DIN-F4 non-rising stem resilient gate valve gland type can be only full open or full close. They are widely used in series of industries, especially in water supply projects, public works, water treatment plant, fire fighting, etc. Prosper Flow can manufacture DIN-F4 non-rising stem resilient gate valve gland type according to the standard of DIN3202 F4 with sizes of 2″~32″ (DN50~800mm).

2. FEATURES

· Full bore design

· Self cleaning & low pressure loss

· Rolled stem ensure smooth thread edges and double thread reduce the closing numbers and torque

· Big enough stem nut ensure not easilt falling off from the disc

· The body is made of ductile iron GGG50, shall not be broken by transportation, collision or installation

· Low torque operation

· Fusion bonded epoxy coated inside and outside

· Good and clear body marking (Castings are from the same foundry with AVK Valve and Spain TALIS)

· 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
