Features of constant flow control valve

Convenient installation and use.

The control part has no complex electric sensing mechanism and is not prone to failure.

The setting is simple, and the adjustment function will be completed automatically after setting.

No manual operation or other power source is required.

Flow Control Valve Working Principle

The flow value in the pipeline is controlled by the change of the opening size of the main valve disc and can be stabilized at a set value. The size of the main disc switch and the opening is controlled by the size of the pilot valve. The media pressure is taken from the downstream side of the throttle plate plus the spring force and the pressure taken from the upstream side of the throttle plate acted on the lower part of the diaphragm respectively. When the flow rate and pressure on both sides of the throttle orifice plate change, the pressure acting on the lower part of the diaphragm Will no longer balance, the diaphragm deformation, the opening of the guide valve change, and the opening of the main valve will also change accordingly so that the flow in the main road will return to the original set value.

Installation and Commissioning of Flow Control Valve

A gate valveand a filter should be installed before the main valve, and a gate valve should be installed after the main valve for maintenance. The guide valve has been adjusted before delivery. If the set flow value is not suitable for the field requirements, the guide valve adjusting screw can be adjusted For specific use, please consult ZECO Valve Group.
