Penumatic Three Ways Flow Control Valve in Diverting / Mixing , PN
64 Bar
PRODUCT INTRODUCTION
1. Description
ZJHQ pneumatic three-way combined flow control valve, ZJHX
pneumatic three-way shunt control valve, by pneumatic diaphragm
multi-spring actuator and three-way valve.
The new type ZHA / B multi-spring actuator replaces the old type
ZMA / B actuator, which has the advantages of low height, light
weight, easy installation and maintenance.
The three-way valve spool structure adopts a cylinder thin wall
window and adopts the side direction of the spool. It can be used
in proportional control valve or bypass regulation, especially in
the fluid temperature control system of heat exchanger in petroleum
industry. One three-way valve can replace two single-seat valves or
two-seat valves, occupying small space, saving installation
pipeline and cost.
Pneumatic three-way control valve is widely used to accurately
control gas, liquid and other media parameters such as pressure,
flow, temperature, liquid level, etc., so as to keep it at a given
value. Confluence valve can mix two kinds of fluids through
three-way valve into one kind of fluid flow, and diversion valve
can divide one kind of fluids into two ways through three-way
valve. When the diameter DN < 65mm, due to the small unbalanced
force of the medium acting on the valve spool mouth, the diversion
valve can be replaced by a confluence valve.
This series of products has two kinds of three way confluence and
three way shunting. Nominal pressure PN1.6, 4.0, 6.4 MPa; Nominal
diameter DN25-300, suitable for fluid temperature - 60 to 450 °C,
permissible leakage level IV, flow characteristics of linear,
parabolic two kinds.
