gate valve Z40H

gate valve Z40H

Gate valve Z40H 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 do not use frequently and keep the disc full-or full-closed. But it does not 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 specifications of gate valve Z40H are:(1) Operated way: Handwheel, Gear, Pneumatic, Electric;(2) Structure Type: Rising stem(wedge and paralled), Non-rising stem wedge, single disc, double disc;(3) Test Standard: ISO5208, API598, API 6D, JISB2003, BS 6755;(4) Face to Face Std.: ASMEB16.10, API 6D, JISB2002, DIN3202, BS2080;(5) Design & Manufacture Std.: API600, API 6D, ASME B16.34, BS1414, JISB2071, JISB2073, JISB2083.

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 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.
