Installation Manual:                                                                                                                                        

For pipe thread connection type gate valve,we should make sure the pipe being vertivcal against the end surface of the valve body when tighten the connection part.our special warning is that we should only wrench the octanal

At the same end of body instead of the other side to avoid deformation so as to affect its normal open function.

For internal thread type gate valve,we should control the length of the external thread at the pipe end in case deformation of the valve body caused by the external thread’s aqueezing the surface of the internal thread so as to affect leakproofness

When connecting the pipe thread type gate valve with pipe thread,the internal thread can be either tapered pipe thread or cylindrical pipe thread,but the external thread must be tapered pipe thread,otherwise it will cause leakage due to loose connection

When installing the pipe thread type gate valve,the sealing material must be clean.

Such obstacles as wall,coupling nut and pipe should not be placed inside the open/close range

When the gate valve handle is parallel to the body,it is open,otherwise,it is close

PP-R gate valve installation instruction:

Remove the coupling nut,PP-R pipe and O-ring from the valve body.

Pull the coupling nut on the pipe in the original direction.

Join the PP-R flange with PP-R pipe with a hot fustion machine,Pull the O-ring in the PP-R flange when it close down.last.tighten the coupling nut with valve body.

Competitive Advantage:                                                                                                                                 

1. Small resistance with the fluid

2. Small force is needed when open and close the valve

3. Unlimited by the direction of flow medium

4. Resistance between the working medium and the sealing surface is smaller than that of stop valve’s when the valve is opened completely
