Needle valve function and parameters

 

Needle valve is a type of valve that can be precisely adjusted and has a wide range of applications, such as cutting for flame cutting The knob for adjusting flame temperature is a needle valve. Instrument needle valve is an instrument measurement pipeline system The important components of the system mainly include globe valves and ball valves, which are used to open or cut off pipes Used for road access. The valve core of a needle valve is a very pointed cone that is inserted into the valve like a needle Seat, hence the name.The main Needle Valve product names of China Needle Valve Network include:EN5-3 WF1/2 Five-valve Manifold,EN5-5 QF-05 Meter Balanced Valve,EN5-6 QFF3 Three-valve Manifold,Electric Soft-sealed Wafer Needle Valve,EN5-8 1151 Three-valve Manifold,EN5-9 1151 Three-valve Manifold,EN5-10 SF-2B Integrative Three-valve Manifold

 

Compared to other types of valves, needle valves can withstand greater pressure and have better sealing performance Needle valves are commonly used for sealing gas or liquid media with low flow rates and high pressures It is most suitable to use it in conjunction with a pressure gauge, as most needle valves are designed with threaded connections.
