Specialityvalve is one of the best Gate Valve Manufacturer in India. Gate Valve is a valve that opens by lifting a barrier out of a path of a fluid. It is designed with a fully open or closed service. Operation of a gate valve is performed either clockwise to open or clockwise to close. The gate moves up or down on the threaded part of the stem. Gate valves should not be used for regulation or throttling of flow because accurate control is not possible.
The high velocity of the flow in the partially open valve may cause erosion of the disc and seating surfaces and creates vibration and noise. 360° surface contact is required between the disk and seats when the valve is fully closed to achieve proper sealing. A gate valve consists of a valve body, seat and disc, a spindle, gland, and a wheel for operating the valve.
The gate valve allows the media to flow through unobstructed or stop the fluid flow. It passes straight through the unobstructed which induces minimal pressure over the valve. The unobstructed bore of the gate valve also allows for a pig’s massage in cleaning the piping procedure. Gate valves are commonly referred to as sluice gate valves.
Specialityvalve is the leading Gate Valve Manufacturer in India which provides high-performance gate valves that can meet the demand of a wide range of pressure and temperature conditions. We offer quality gate valves that cater to the requirements of many customers.
