1. The valve disc moves up and down The connecting pipe connects the upper chamber with the valve outlet, allowing the valve disc to rise and fall Reduce impact and vibration, and achieve full stroke of the valve
2. The valve body is Y-shaped with low resistance, and the guide ribs are welded with hard alloy. The guide sleeve is made of stainless steel material, and the valve cover operates flexibly
3. Adopt pressure self tightening seal Reliable sealing
4. The sealing surfaces of the valve disc and valve seat are both made of cobalt based alloy welding, which has high hardness, corrosion resistance, abrasion resistance, and durability

The Power Plant Check Valve has small fluid resistance, the medium channel inside the valve body is straight through, and the flow direction of the medium does not change when it flows through the check valve. The pressure self-tightening seal is used, and the two ends of the valve are usually welded. The valve flap closes quickly, the water hammer pressure is small, the body structure is simple, the production process is good, the sealing performance is good, and the sealing surface is less eroded when fully opened. A wide range of applications.
This product is a new type top entry combination ball valve,the seat can be installed and move around the body. Through the thread, the outer margin of the seat connected to the retainer ring. There is spring on the support cover, which installed on the valve body, and the retainer ring can compress spring.
The “Double Block and Bleed Isolation Philosophy” requires two in-line isolation valves and a bleed valve, used to drain or vent trapped fluid between the two closure elements in order to safely isolate safely the downstream pipe. This feature can be achieved with one single valves c/w a bleed port between the obturators.
