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 Features

Low torque operation
Rubber encapsulated wedge
Clockwise closing direction
Fusion bonded epoxy coated inside and outside


Product Advantages

1. The body is ductile iron,high level than national stanard.Tensile strength is 450Mpaelongation 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 frictionprevent 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.


Fluid resistance small, sealing surface of erosion and erosion by the medium.
1.The traditional gate is often in the water after washing pipe from outside, such as stone, wood, cement, paper scraps, sundry sedimentation on the bottom of the valve such as the slots, easy to cause cannot close tightly and form slack phenomenon, soft-sealing gate valve using the same as the pipe at the bottom of the flat design, not easy to cause debris deposition, the fluid flow unimpeded.
2.Over all plastic bags, the valve is made of high quality rubber, outsourcing, the whole domestic first-class rubber vulcanization technology make the valve to ensure accurate after vulcanization of geometry size, and rubber and ductile iron valves, then fall off not easily and elastic memory preferred. Corrosion resistance, the body USES the powder epoxy resin coating, can prevent the body of the corrosion and rust, and can be used in the sewage system. Not easy to fracture in the past the traditional cast iron gate valves often caused by external things hit, collision or overlapping phenomenon such as fracture. Due to the body to nodular cast iron, this kind of situation has been greatly reduced.
3.Three type "O" ring seals, because stem with three type "O" ring sealing ring seal design, can reduce the frictional resistance when switch, sharply reduce leakage phenomenon and can not replace the sealing ring of water construction. Help to drink - due to the inner body with non-toxic, epoxy resin coating, both inside and outside surface of the gate is fully coated with rubber without water rust or corrosion phenomenon, to drink. Precision casting body, the body USES the precision casting, precise geometry size inside the body to ensure the valve without the need for any finish sealing. Made from light weight - ontology with ductile casting, weight than traditional gate about 20% ~ 20% reduction in weight, easy installation and maintenance
