Are there any manual needle-type control valves for gas regulation?

2017-03-14View Original

Thread Content

The medium transported is natural gas; the design/operating pressure is 25/20 MPa, the pipe diameter is DN40, and the flow rate control range is 50–300 Nm3/h. Manual needle valves are intended for use in this application, with DN25/PN250 specifications. Which manufacturer’s products are of good quality, and do they have any proven track records of successful use?

China Nuclear Su Valve is quite good, and its price is not high either.
