Introduction

Product introduction
The valves disc is rubber-packed to get excellent sealing effect by the rubber's resilient deformation.
Non-rising resilient seated gate valves solve the problem in general gate valves such as leakage, rusting etc.
and saves installation space. It is used widely in tap water industry, sewage treatment, shipping construction,
petroleum, chemicals, food, pharmacy, textile, electric power, metallurgy and energy system's pipeline to adjust and shut off fluids.

Product Advantage

1.The body is ductile iron,high level than national stanard.Tensile strength is 450Mpa,elongation is large than 10%,can not be broken easily when transport.

2. Both inner and out part is epoxy coating, the thickness is 250μm minimum,can prevent rust well,can be used in  sewage system. 

3 The wedge is coated with EPDM, the EPDM proportion can reach 50%,steable and good resilient;

4、 3 O rings are used on 2Cr13 stem,can reduce friction,prevent leakage,can change sealing ring with stop water

5、The stem use brass, operate easily,prevent block

6、Every link, from workblank to the finished product packaging will be inspected strickly.

7、BUNDOR Product quality is covered by China Pacific Insurance with two million dollors. Bundor Valve, Two Years Warranty, Pay Two Back If One Bad. Any quality problems of the product itself, we will pay without conditions.

 

Standard Test

Shell test

The cold test of the valve body, which is connected with the valve body and the valve cover, 

is carried out to test the structural strength, pressure resistance and compactness of the 

valve housing, including the whole housing in the fixed connection

Closure test

Test of sealing performance between valve opening and closing parts and seat seal, between 

valve body and valve seat

Test pressure

The display pressure of the valve lumen during the experiment

Test fluid

Liquid or gas for pressure test of valves

Test fluid temperature

The temperature of the liquid or gas used for the pressure test of the valve shall be in the 

range of 5-40 unless otherwise specified

Resilient seats

Seals made of non-metallic elastic materials, solid and semisolid lubricants, etc.
