HG61A micro resistance butt welding butt welding micro check valve blocking purposes: HG61A- (160 ~ 400) spherical valve straight-line reference to API and CVA related standard design and production of a new high-pressure valve. UHP check HG61A oilfield special valve for temperature no higher than 120 ℃, working pressure of not more than 40MPa of water, oil pipeline, used to control the opening and closing one-way medium, medium to prevent backflow. Resistance butt welding micro check valve structure characteristics and working principle EHV check HG61A oilfield special valve made of stainless steel with high hardness ball valve, stainless steel with high hardness seat, using line contact seal, so reliable sealing performance and durable. The main valve body and pressure parts were confirmed by detailed strength checking, the use of safe and reliable. UHP check HG61A oilfield special valve is normally in a closed state, the pressure in the inlet end of the line media, and to overcome the resistance of the spring causes the valve to open. When the pressure is lower than the inlet end of the media outlet end, spring will push the valve spool leaving the valve closes to prevent backflow media, beginning and ending back role. UHP check valve oilfield special thanks HG61A spring support spool, so the use of vertical or horizontal installation can be installed. Ordering :( national standards) a, A: product name, model number, nominal diameter B: medium and temperature, pressure range C: Are there attachments, delivery, special requirements so that we can correct for your selection. Second, if the company has been selected by the design of the valve type, please directly contact our sales center to order according to the valve parameters. Third, when you use the occasion is very important or the environment is more complicated, please provide design drawings and detailed parameters, our engineers specialists will concentrate on your review and analysis.
