Gas PE gate valve,PE Gate Valve,Gate Valve

(1) Valve body, valve cover. Ram and other pressure parts are steel materials, will not be deformed due to the length of time and temperature changes, so that the seal is reliable, and there will be no phenomenon that can not be opened or closed.

(2) The floating structure behind the seat has a rubber seal ring or spring preload force, even under very low pressure the valve can be sealed.

(3) The sealing surface of the seat is inlaid with RPTFE, with soft and hard double sealing. The parallel gate is always in line with the sealing surface of the seat during the switching process, which can remove the stolen goods on the gate and make the sealing more reliable.

(4) When the valve is fully opened or fully closed, the sealing surface of the valve seat is not washed by the medium, which effectively protects the sealing surface.

Double isolation function: When the valve is closed, the two sides are sealed, the left and right media are completely cut off to seal, and there is no pressure in the middle cavity.

Elastic seal: The valve seat is a floating double valve seat, the outer circle adopts the principle of O-ring sealing piston effect, and the elastic preload force behind the valve is compensated for sealing. The parallel gate only needs to contact the sealing ring in place, and no additional force is required to seal it.

Replaceable valve seat: The valve seat is installed on the valve body for floating structure, can be disassembled and replaced online, and two-way sealing.

Packing seal: the valve cover packing box adopts the piston principle of the seal sleeve O-ring and V-type pressure seal structure, without adjustment, opening and closing is very light, so that the valve packing performance is more reliable, to solve the general valve packing is the most easy to leak, and the packing structure makes its opening and closing torque is far less than PE ball valve.

Release function: The release pipe can be set on the left and right sides of the valve body, thus replacing the release pipe set by the pipeline, saving cost.

Closed indicator: The fully closed opening and closing indicator can maintain the basic degree of valve opening and closing

Anti-corrosion measures: The outer surface of the valve is anticorrosive with epoxy coal asphalt, which can have the same life as the pipeline.

This valve is mainly suitable for urban gas pipe network transmission and cut-off medium, can be buried underground, directly connected with PE pipe, no need for steel-plastic conversion joint transition, reduce project cost. Only a small valve chamber is built on the valve cover, which can be fully operated and maintained on the ground. The sealing performance is good, the flow resistance coefficient is small, and the operation and maintenance are convenient. Long service life, is natural gas, city gas, liquefied gas

PE pipe connection: the two ends of the valve are PE pipes, using the principle of steel-plastic conversion joint, and the valve into one, so that the PE pipe is directly connected with the electric melt sleeve, simple and convenient, and the middle connection (valve body valve cover connection) : the middle connection bolt adopts the countersunk hole design to ensure that the bolt has no leakage and improve the anti-corrosion performance of the valve.

Packing of Standard Packing: 

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request. E FORUs’  is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
