8 ways to solve the vibration problem of the control valve

1. INCREASE THE STIFFNESS METHOD For oscillation and slight vibration, the stiffness can be increased to eliminate or weaken. For example, it is feasible to use a spring with a large stiffness and a piston actuator. 2.  INCREASE THE DAMPING METHOD Increasing the damping increases friction against vibration. For example, …

4 Major Elements to Selecting a Suitable Regulator Valve Actuator Type and Specification

DRIVING ENERGY The most commonly used driving energy source is the power source or fluid source. If the power source is selected as the driving energy source, the three-phase power source is generally selected for the large-size valve, and the single-phase power source is selected for the small-sized valve. General electric …

The reason for and treatment of the pneumatic control valve is not tight

Pneumatic control valves often present some troublesome problems during use. For example, if the pneumatic control valve is not tight and the door is not tight, what should I do? Under normal circumstances, if it is not critical, first check to see if the valve is closed. If it is closed, it is …

How to correctly choose the positive and negative ways of the pneumatic control valve

The working model of the pneumatic control valve is air opening and gas closing. The opening of the air opening valve increases with the increase of the signal pressure. When there is no pressure signal, the valve is in the fully open state, and the gas closing is the opposite. Reasonable selection …
