resilient seated gate valve

A gate valve is a valve designed with the use for getting straight-line flow of fluid with minimum restriction. The goal can be realized by raising a gate or a wedge out of the fluid path. It is necessary to remember that the gate valve can not be used to regulate the flow of fluid. A resilient seated gate valve is the gate valve designed with resilient seat. The resilient seat can maintain the flexible operation. Generally speaking, the valve is composed of body, seat, stem, gasket, bonnet and so on. Various kinds of materials can be used to produce the valve. For example, the body and bonnet of resilient seated gate valve can be made of GGG40 or GGG50, the wedge can be made of GGG40, GGG50, NBR or EPDM, and the nut of the valve can be made of brass 59-1.

The design of resilient seated gate valve conforms to the requirements of DIN3352, BS5163, and SABS664/665. If the wedge is made of NBR, the working pressure should be equal to or less than 80 degrees centigrade, and if the wedge is made of EPDM, the working pressure should be equal to or less than 120 degrees centigrade. The resilient seated gate valve can be operated by a hand wheel, a nut, an extension stem or a gear operator. The suitable media for the gate valve include water and neutral liquids. With the wider and wider application of the valves, many companies have started the production of the industrial valves. Qingdao Huaguan Valves Co., Ltd. is one of the professional manufacturers of various valves including resilient seated gate valve. The company can provide high-quality products for the clients in need.
