Resilient Seated Gate Valve Detail / Feature / Application

  • The Resilient Seated Gate Valve disc is rubber-packed to get excellent sealing effect by the rubber's resilient deformation.

  • Non-rising resilient seated gate valve solve the problem in general gate valves such as leakage, rusting etc. 

  • Low torque operation, Rubber encapsulated wedge, Fusion bonded epoxy coated inside and outside.

  • Resilient Seated Gate Valve Application: Pipelines to convery oil and storage facilities, Water and wastewater technology, The wellhead device of the oil and gas expoitation, Water engineering.

  • Each Resilient Seated Gate Valve will be carried out appearance, material, air tightness, pressure and shell testing before leaving the factory; unqualified products are resolutely not allowed to leave the factory.

Resilient Seated Gate Valve Introduction

Resilient seated gate valves made of speclal rubber elastlcly  full wrap-plece valve structure, and the general absence of gate  leakage or rust compared to other phenomena. Overcome their  common seal bad, elastic fatigue, wear rubber aging and Sealing ruts and other defects. Produced by ths elastic saeling full  compensation of small quantities of deformation to achieve a  good sealing effect. It can be widely used in water supply,  petrochemical, metallurgy, shipbuilding, food, pharmaceuticals  and energy systems and other fluid line is used as a regulator  and shut-off devices.

Resilient Seated Gate Valve Features

1. The overall package of plastic: the spool and the latest high-performance rubber vulcanization technology overall coating. laminating are tight. accurate geometry, rellable sealing and long service life.

2. Light weight: body ductile iron material, gate valve to reducs weight than tha average 25%, easy installation and maintenance; gate valve maximum opening helght is generally low 60mm ~ 280mm, can be installed where space is limited.

3. Flat style seat: The bottom of the pipe the same flat style seat design, does not produce debris accumulation, flow channel unimpeded and reliable sealing.

4. Corrosion resistance: the valve cavity using non-toxic epoxy powder coating, inner parts mining copper alloy and stainless steel to prevent corrosion and rust.

5. The three 'O' seal: the use of the stem seal O-ring seals, friction is small, lightweight and watertight gwitch.

FAQ of Resilient Seated Gate Valve

The following checks should be carried out during installation: 

Whether the connecting bolts are evenly tightened.

Check whether the packing is tight.

After compaction, the sealing of the packing should be ensured and the rotation of the valve stem should not be blocked.

Check regularly after installation:

Wear of sealing surface

The wear of the trapezoidal thread of the valve stem and the valve stem nut.

Wear of trapezoidal threads of valve body and bonnet nuts.

Wear of trapezoidal threads of valve body and bonnet nut.

Whether the packing fails due to long use.

After the valve is overhauled and assembled, a sealing performance test must be carried out. After each overhaul, the overhaul will be recorded in detail for future reference.
