Gate valve application: chemical, petrochemical, petroleum, paper, mining, electricity, liquefied gas, food, pharmaceutical, water supply and drainage, municipal, mechanical equipment supporting, electronic industry, urban construction and other fields.

Stainless steel gate valve, Z15W gate valve, thread gate valve, internal thread gate valve function: gate valve can only be fully open and fully closed function, can not be adjusted and throttled.

Applicable media: oil, water, steam, etc

Gate valve application: chemical, petrochemical, petroleum, paper, mining, electricity, liquefied gas, food, pharmaceutical, water supply and drainage, municipal, mechanical equipment supporting, electronic industry, urban construction and other fields.

Gate valve features:

(1) Low flow resistance. The medium channel inside the valve body is straight through, the medium flows in a straight line, and the flow resistance is small.
(2) less effort when the globe valve is opened and closed: whether it is open or closed, the direction of the ram movement is perpendicular to the direction of the medium flow.
(3) Large height, long opening and closing time. The opening and closing stroke of the gate is large, and the fall is carried out by the screw.
(4) Water hammer phenomenon is not easy to produce. The reason is the long shutdown time.
(5) The medium can flow in any direction on both sides, is easy to install, and both sides of the channel are symmetrical.
(6) The length of the structure (the distance between the two connected end faces of the housing) is small.
(7) Simple shape, short structure length, good manufacturing process, wide range of application.
(8) Compact structure, good valve rigidity, smooth channel, flow resistance number is small, sealing surface is made of stainless steel and cemented carbide, long service life, PTFE packing, reliable sealing, light and flexible operation.

Gate valve installation precautions:

(1) Handwheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited.
(2) The double gate valve should be installed vertically (that is, the valve stem is in a vertical position and the handwheel is at the top).
(3) Gate valves with bypass valves should be opened before opening the bypass valve (to balance the pressure difference between the inlet and outlet and reduce the opening force).
(4) The gate valve with the transmission mechanism shall be installed according to the provisions of the product instruction manual.
(5) If the valve is often used, lubricate it at least once a month.

Other technical parameters Note:

(1) Gate valve prices vary by caliber, material and pressure.
(2) Connection form: thread, flange, welding, etc.
(3) Transmission mode: manual, gear drive, pneumatic, electric, etc.
(4) Caliber from DN6-DN10; Pressure from 1.0MPA - 64MPA; Temperature -20-300℃.
(5) Material: carbon steel, stainless steel, alloy steel, chromium molybdenum steel, low temperature steel, ductile iron and other special materials.
