CW617/59#57# 1/2" -4" Hot Forging Female Thread High Pressure Brass Plumbing Gate Valve DN70 Design Manual Straight Sliding Type
Main technical parameters:
1. We select high quality copper material and apply hot forging process in the production process.
2. The main working medium are water,oil.gas.etc.
3. Working temperature range from -20℃ to 120℃
4. Thread standard:ISO228
Each nominal working pressure of our gate valve are 2.5Mpa,2.0Mpa and 1.6Mpa
Description(structure of gate valve):
A.Handwheel B.Gland nut C. Gaskets D. PTFE E.Bonnet F. O ring G. Gaskets H. Stem I. Wedge disc J.Body
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.
Applicable medium: water, oil, gas, steam and so on.such as machinery and equipment, chemical equipment, general parts, industrial equipment, plumbing equipment, papermaking equipment, pharmaceutical equipment, general equipment, petrochemical equipment, power equipment, powder metallurgy equipment, mining equipment, electronic industry and other municipal.
