The difference between these two kinds of products, mainly lies in the control valve needs both external sources such as power supply or air), and the need to do driver can accept foreign control instrument signal to change in the valve closure pieces of relative positions, so as to realize the change fluid flow. And self-reliance type pressure regulator is neither need foreign energy, and does not need to accept foreign control instrument signal, only by being transported media pressure signal, can achieve pressure to adjust.
Paddle type pressure regulator characteristics due to paddle type pressure regulator without outside drive energy, so the product’s operation force smaller, it has the following characteristics.
1, self-reliance type pressure regulator without plus energy, can in no electricity non-air occasions work, convenient and save energy.
2, pressure piecewise range is finely and cross each other, adjust the high precision.
3, pressure setting during operation can be continuous Settings.
4, the valves pressure regulating valves, the former after after pressure with the pressure between now ~ vexed than for
5, rubber diaphragm type testing, actuators, high accuracy, action quick.
