Manual knife type gate valve

The design specification 

Design criteria: ASME B16.34, GB/T 12234, JB/T8691 

Structure length: GB/T 15188.2 

Connection standard: ASME B16.5, GB/T 9113, JB/T79 

Pressure test: GB/T 13927, API598 

Pressure - temperature rating: API6D, GB/T 26480 

Characteristics 

1.Super short structure length and saving materials can greatly reduce the overall weight of piping system. 

2.Small footprint and effective support for pipeline strength can reduce the possibility of pipeline vibration. 

3.With the austenitic stainless steel, the anti-corrosion performance of the gate is greatly improved, which can effectively prevent the sealing leakage caused by the corrosion of the gate. 

4.Upper sealing filler adopts flexible PTFE, which is reliable and easy to operate. 

The gate has the function of the knife, which can effectively break the various kinds of sundries in the medium. 

6.If a hard sealing stainless steel material is used, the valve can be used for spraying welding, which can be used to expand valve temperature and pressure.
