Gate valve
The gate valve is used for cut-off the medium, when full open the flow through the whole pipe, when the media running, there have a minimum of pressure loss. Gate Valve is usually used for the working environments which donĄ¯t use frequently and keep the disc full-or full-closed. But it doesnĄ¯t applicable to regulator or reducing the medium. When the flow of medium is high-speed, the disc to open at local conditions can cause the vibration of the disc, and the vibration damper may damage the disc.
The gate valve is divide into two big types by sealing surface configuration, include wedge-type gate valve and parallel-type gate valve, wedge gate-type valve can be divided into: single-disc gate valve, double-disc gate valve and flexible-disc gate valve; the parallel-type gate valve can be divided into single-disc gate valve and double-disc gate valve. According to location of the thread on the stem, the division can be divided into rising gate valve and non-rising gate valve.
