Product Description

Introduction

A Multifunctional Pump Control Valve is a specialized hydraulic control valve widely used in water supply systems, especially for pump outlets in high - rise building water - supply setups and other water - feeding systems. 

Specification

Applications

It is mainly used in water supply systems, especially in the water - supply systems of high - rise buildings, as well as in industrial water - supply and drainage systems, fire - fighting water supply systems, etc. In these systems, it can ensure the safe and stable operation of the pipeline, prevent  (medium backflow) and water hammer phenomena, and protect equipment such as pumps.

Advantages
No Need for Additional Electrical Control: It uses the water pressure difference between the valve and the pump as the control power, eliminating the need for electrical control, other power sources, and manual operation, as well as oil pressure equipment. This simplifies the system and reduces costs.
Good Water Hammer Prevention Effect: Integrates the technologies of slow opening, check - quick closing, and slow closing to eliminate water hammer, effectively protecting the water supply pipeline and pump from the damage caused by water hammer.
Convenient Operation: It can automatically complete the control functions in sequence as the water pump starts and stops without the need to configure an additional electronic control system for the valve.
Efficient and Energy - Saving: Has a large flow rate and small pressure loss. For example, the diaphragm type is suitable for valves with a diameter below DN600, which can save energy while ensuring normal water supply.
