Non-Rising Stem Design Resilient Seat Gate Valve

Concealed stem design: The valve stem nut is connected to the gate plate, and when the valve is opened and closed, the valve stem only rotates without lifting (driven by the handwheel or gearbox), saving installation space and suitable for underground or narrow environments.

Elastic soft seal: The gate plate is covered with elastic materials such as rubber or polyurethane (integral encapsulation process), forming a tight fit with the valve seat, with good sealing performance, and can compensate for slight wear.

Valve body material: usually cast iron (HT200, QT400), ductile iron or stainless steel, and the inner cavity is coated with epoxy resin for corrosion protection.

Design without diversion holes: Some models of gate plates are solid structures, suitable for fully open/fully closed working conditions, and not suitable for regulating flow.            

The above four items are the basic structure of Non Rising Stem Design Resilient Seat Gate Valve

Application

Municipal water supply: main pipeline network, secondary water supply system.

Fire protection system: wet/dry fire protection pipeline.

Building pipelines: Building water supply and drainage, HVAC circulating water.

Industrial field: sewage treatment, chemical media (sealing material needs to be selected according to the medium)

What are the core features of the Non-Rising Stem Design Resilient Seat Gate Valve?

Bidirectional sealing: It can effectively seal under both forward and reverse pressure, without being restricted by the flow direction of the medium.

Low flow resistance: When fully open, the channel is straight through, with low fluid resistance, suitable for high flow situations.

Corrosion resistant and durable: The valve body is often coated with epoxy resin, and the rubber seal is corrosion-resistant and has a long service life.

Easy maintenance: The sealing ring can be replaced, and some designs support online maintenance without disassembling the valve.

Applicable media: non corrosive media such as water, sewage, air, etc. (temperature generally≤80℃).
