resilient seated gate valve

Low Torque Operation Resilent Seated Gate Valve, Suitable For Water

How do we ensure finished product quality (FQC inspection)

1. Visual Inspection

2. Material Grade Measurement

3. Dimension Inspection

4. Roughness Detection

5. Roughness Detection

6. Leakage Test

Feature: 

1. Stem sealing
    Stem sealing replaceable under pressure with three independent stem seals:
    NBR wiper ring protects against dirt from outside.
   4 pcs of O-ring protects the stem and prevents leakage.

   Replacing stem seals under pressure is available.

2. Vulcanized wedge
    The ductile iron core is fully vulcanized with drinking water approved EPDM rubber internally and externally. No iron parts are exposed to the medium and the excellent rubber vulcanization prevents corrosion underneath the rubber. Nylon Guides in the wedge and on the valve body ensure a uniform closure regardless of high pressure.
