Specialityvalve is one of the biggest producer and supplier of Gate valve Manufacturer in India.

Gate Valve is a control valve that either allows the fluid flow or stops it depending upon our use. It is a most common valve for water valve systems. It is a linear motion valve that starts or stops the flow. It got its name from the element sliding into the flow stream to provide shutoff, hence acting like a gate. Thus it is used either in the fully closed or fully open positions.

Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid. When the gate is fully opened it enables the gate valve to offer straightway flow with very little pressure drop.

Gate Valves are also called as Sluice Gate Valve. Automated Gate Valve also exists which are either electric or pneumatic actuator, but as manual gate valve are cost effective hence it is affordable and as gate valves are used lesser.

Gate valves should not be used for regulation or throttling of flow because accurate control is not possible.

Components of Gate Valve

● Body

● Bonnet

● Body Seat

● Stem Nut

● Yoke Nut

● Stem

● Handwheel

● Gasket

Working of Gate Valve

The main three components of Gate Valve are: body, bonnet and stem

When the handwheel is rotated which rotates the stem and due to it there is vertical movement of the gate via threads. They are considered multi-turn valve as it requires more than 360 degree to fully open the gate. When the gate is lifted from the flow path, it is open and when it returns it is closed and hence the flow is stopped.

the gate and the valve.

Forged steel gate valve flanged is just a gate valve which with a flange.

A gate valve is positive shut off and used for on of off . A globe valve is for throttling

A Knife Gate Valve is used to slice through sludge /sewerage and a gate is used fro normal positive shut off
