China High temperature metal seated gate valve Manufacturers, Suppliers, Factory

A pneumatic lug butterfly valve is a mechanism that regulates the flow of materials within large pipe diameters by the quarter-turn rotation of a disc. The valve is driven by pneumatic and connect with the pipe by lug.

ASME gate valve is suitable for ANSI class150 ~ 2500, PN20 ~ 42, JIS10 ~ 20K, working temperature - 29 ~ 425 ℃ (carbon steel) and - 40 ~ 500 ℃ (stainless steel),. ASME Gate Valve is used to cut off or connect the medium in the pipeline. By selecting different materials, ASME Gate Valve can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing medium, urea and other media.

You can rest assured to buy customized 2 Inch Female Thread Brass Ball Valve from us. We look forward to cooperating with you, if you want to know more, you can consult us now, we will reply to you in time!

Once the valve disc open, there is no contact between the seat and the sealing surface of the valve disc. And Thread Globe Valve has so reliable switch off reaction, that the valve is used for cutting off or regulating flow. The valve is apply to cutting off or connecting the pipeline medium under various working conditions such as petroleum, chemical industry, metallurgy, electric power, papermaking, pharmaceutical, food, water treatment, petroleum, chemical industry, thermal power station, etc.

1. The double flow direction can bear pressure to realize the installation mode without flow direction restriction. 2. The design of all metal seal, the seat and sealing ring adopt steli alloy surfacing technology to solve the problem of poor sealing performance of butterfly valve under severe working conditions such as high temperature, high pressure and low temperature. triple eccentric butterfly valve can withstand pressure up to 2500 pounds, and the temperature resistance is as low as -196 ℃ to 850 ℃, the seal reaches 0 leakage and the control ratio is up to 100:1. 3.The triple eccentric butterfly valve seat and valve body are designed separately, and the valve plate and sealing ring are designed separately. The products can be matched and interchanged. The whole valve will not be scrapped because of the seal wear problem. triple eccentric butterfly valve can be used normally only by replacing the valve seat and sealing ring, thus reducing the use cost.

Motorized Butterfly Valve With Actuator Operator is a valve used for flow regulation in large pipe diameters in which the disc takes the form of disk. Operation is similar to that of a ball valve. A plate or disc is positioned in the center of the pipe. The disc has a rod passing through it that is connected to an actuator on the outside of the valve.
