Project Case



Will you choose gate valve?


Why does wesdom's gate valve have an inverted seal design?

When the valve plate is fully open, the top of the valve plate is in contact with the valve cover. Without stopping the water, the bolts, valve cover and nuts can be disassembled for seal replacement and repair.

Provide convenience for the company's after-sales service in emergencies and special circumstances, and can urgently solve end-user emergencies.

Inverted sealing structure

No inverted sealing structure

Once the nut becomes loose and water leaks, whether it is on a holiday or late at night, the water needs to be shut down immediately for repairs, which will cause extremely bad consequences.

Valve plate features

The upper part of wesdom's valve plate adopts a fully enclosed structure, and the stability of nut fixation is better.

The two sides of the valve plate are double rib structures, the valve plate is wide, the unilateral pressure offset is small, and the torque is light. The static pressure test can achieve two-way sealing and no leakage of static pressure;

Deformation of the inner cavity can be compensated.

Other products:

The valve plate nut of the lower opening structure may be pulled off, causing valve failure and causing customer complaints.

No double rib structure, poor static pressure sealing, short service life.

Valve plate features

Middle head gasket

WESDOM'S gate valve: The right-angled trapezoidal design better solves the sealing problem of the valve cover and valve body.

Other products: Rectangular middle head gasket, easy to deform and leak under pressure.

Middle head gasket

Circlip design

Effectively solve the problem of loosening of copper nuts due to excessive operating torque.

Dust jacket, effectively protects copper nuts and circlips.

Circlip design

"O" rings

WESDOM'S products: The copper nut is internally screwed to the valve cover, and there are 2 "O" rings on the inside and 2 on the outside.

An "O" ring on the valve stem

Excellent sealing and greatly reduced valve stem wear

Other products:

Nuts are easy to loosen

Only one "O" ring

Valve stem has no “O” ring seal

Stem of gate valve

The whole stem is formed by stew-pressing in one piece to enhance the strength of the valve stem. The thread of the valve stem adopts double-headed thread to reduce the torque.

Special design of handwheel

WESDOM'S products: Ergonomics, better use experience, compared with other handwheels, improve product quality and customer satisfaction.

Other products: Made of pressed iron sheet, it is easy to corrode and is easily damaged under high torque.

Special design of handwheel

WESDOM'S products: The flow port of the channel is larger than the diameter, which can meet the need for opening holes.

Other products: In order to save costs, some merchants' products reduce weight and reduce the inner diameter.

① The quality of batch products is basically the same as that of samples, with strong gloss and full color.

② All products are sprayed with non-toxic epoxy plastic powder certified by WARS, and each product can pass the safe drinking water certification.

③ Before each product leaves the factory, it must pass the inspection in accordance with international standards before leaving the factory.
