cast steel flange gate valves and stainless steel flanged gate valve gate valve series valve dosage of customers most of the species, so what's the difference between them?

first we explain what is the gate valve: gate valve open-close part is ram, ram movement direction perpendicular to the direction of flow and the valve can only be fully open and close, not to adjust and throttling. Sealing face has two gate, two of the most commonly used mode gate valve sealing surface form a wedge, the wedge Angle vary with the valve parameters, usually in the form of 50, when the medium temperature is not high for 2 & deg; 52 ' 。

wedge gate valve of the damper can be made into a whole body, is called a rigid disc; Can also make it generates trace of deformation of ram, in order to improve the manufacturability, make up for the sealing surface Angle in the process of our processing deviation, this damper is called elastic disc.

stainless steel gate valves and cast steel gate valves difference:

1, gate valves, stainless steel, corrosion resistance, durable! Cast steel gate valves, over time, rust and corrosion will be over in a period of time.

2, stainless steel, from the aspects of quality of a material is better than cast steel, heat resistant, sealing is better than cast steel. Just beautiful interior are using stainless steel, but the price will be more expensive than stainless steel. Economical industry or cast steel.

no corrosion rust on 3, stainless steel, cast steel corrosion.

to later, its use effect will be bad, and short service life.

as a domestic high-end valve manufacturer, has been in response to national policy and called for, committed to research and development, manufacture, electric butterfly valve, stainless steel ball Industrial Valves, discharge valve, electric gate valves, stainless steel gate, stainless steel valve, stainless steel check valve, high pressure gate valves high-quality let customer trust of good Industrial Valves, the valve to keep traditional valve product sales profits to escort for the innovation research.

Nowadays, the adoption of double flanged gate valve in os & y valve fire protection industry is quite common.
