Horizontal check valve is also called check valve, which prevents the medium from flowing back in the pipeline. Horizontal check valve that opens and closes by the medium flow and force is called check valve to prevent the medium from flowing backward. Check valve belongs to automatic valve, mainly used in the pipeline of medium flow in one-way way, only one direction of medium is allowed to flow, so as to prevent accidents.

Non return butterfly check valve is a one-way valve, is also an automatic valve, non return butterfly check valve only allows media to flow in one direction, and prevent media backflow. Non return butterfly check valve works automatically. Under the action of medium pressure flowing in one direction, the valve disc opens and the medium passes through; When the medium flows in the opposite direction, under the action of medium pressure and the self weight of the valve disc, the valve disc closes, thus cutting off the medium flow.

Signal Butterfly Valve is suitable for harsh environmental conditions.Signal Butterfly Valve is convenient for repair and maintenance.No deformation at different temperatures.

The Electric Three Way Ball Valves are the most common types of ball valves that driven by electric actuator . The Electric Three Way Ball Valves have three ports or connections for pipe.

1. The double flow direction can bear pressure to realize the installation mode without flow direction restriction. 2. The design of all metal seal, the seat and sealing ring adopt steli alloy surfacing technology to solve the problem of poor sealing performance of butterfly valve under severe working conditions such as high temperature, high pressure and low temperature. triple eccentric butterfly valve can withstand pressure up to 2500 pounds, and the temperature resistance is as low as -196 ℃ to 850 ℃, the seal reaches 0 leakage and the control ratio is up to 100:1. 3.The triple eccentric butterfly valve seat and valve body are designed separately, and the valve plate and sealing ring are designed separately. The products can be matched and interchanged. The whole valve will not be scrapped because of the seal wear problem. triple eccentric butterfly valve can be used normally only by replacing the valve seat and sealing ring, thus reducing the use cost.

Cast iron center line butterfly valve has excellent bidirectional sealing performance and low torque, machining performance.Flange connection of Cast iron center line butterfly valve installed easily, vertical and horizontal installation are all right.
