Product Characteristics

1.Female thread vertical check valve has short structure, small size and light weight.

2.Female thread vertical check valve disc closes quickly, water hammer pressure is small.

3.Internal thread vertical check valve flow channel is smooth, fluid resistance is small, action is sensitive, sealing performance is good.

4.Internal thread vertical check valve is easy to install, can be used in horizontal.

5.The internal thread vertical check valve valve plate adopts the design of two torsion springs on the dual plate, which can make the valve plate close quickly by itself.

6.The internal thread vertical check valve can prevent the medium from flowing back and eliminate the strong effect of water hammer due to the rapid closing effect.

Advantages

1.Prevent the rotation of the water meter caused by unstable water pressure, air bags, etc.;

2.It can prevent the hot water at home from flowing back when the municipal pipeline stops water, and destroys the plastic watch core of the water meter;

3.It can prevent tap water from being polluted;

4.It can prevent tap water from flowing to the outside pipe. The disadvantage of the check valve is that the fluid resistance is large, and the medium channel in the valve body is relatively tortuous, which is easy to cause water conservancy loss and lead to energy consumption.
