Needle valve: a kind of valve that can be precisely adjusted


We know that the needle valve has very good performance characteristics, mainly in the regulation, circulation and cutting performance. Today we will briefly introduce these three properties of the needle valve.

Needle valve has good regulation performance. In general, under normal circumstances, the adjustment range of the needle valve is in the range of 100 ~ 200, and the adjustment range of the good valve on the market is only 50.

Needle valve has good circulation performance. The flow path of the needle valve adopts a straight-through form, so that the circulation of the medium no longer needs to be turned, which greatly reduces the possibility of medium deposition. Therefore, it is very suitable for places with high viscosity, suspension, pulp and other dirty media.

Needle valve has good cutting performance. One of the biggest features of the needle valve is that the contact between the spherical valve core and the bevel of the valve seat is in the form of line contact, which reduces the contact surface and further reduces the leakage rate of the valve.
