Application :The valve is called SCV-S welding straight-throutgh check valve .which is used for ammonia cold room pipe and
refrigeration equipment, Which control the flow of ammonia by operate the hand wheel of valve.
1.The valve is made through low-temperature alloy precision casting for forging,with Y-shaped structure which can reduce the flow resistance,avoid the calorification,eddy and effusion,decrease the supplement of refrigerant,and meanwhile produce no liquid explosion or flash gas.
2.The six-level sealing structure uses imported materials and can thoroughly avoid leakage,six levels of protection makes the structure more safe and reliable.
3.the valve rod is made of 304 stainless steel which can never be rusted.the surface is nano processed(national patent)which has increased the surface hardness;meanwhile,the RA valve of surface finish is less than 0.03 and friction is almost zero.therefore,under all cases,it can beopen opened and open and closed with pilot wheel
4.Advanced modular design makes it possible to assemble diferent functions of components on the same valve,which is quite convenient and quick.
5.New type of seal structure(national patent)ensures the valve can be effectively closed at any position,greatly improving the safety.
