Products Introduction

The Pipe Force Valve is a new generation of pump control valve, developed by our company’s engineering and technical personnel based on the absorption of micro-resistance slow-closing check valves, hydraulically controlled check butterfly valves, and multifunctional pump control valves, it combines the functions of electric gates, electric butterfly valves, and check valves, and eliminates water hammer hazards through quick-closing and slow-closing actions, thereby protecting the safety of pumps and piping systems, it is widely used in water supply and drainage systems, sewage pump stations, and chemical fluid transportation systems across various industries including electric power, environmental protection, metallurgy, petroleum, petrochemicals, chemicals, water conservancy,municipal infrastructure,and food.

 

Products Feature

Diverse functions: with globe, check, water hammer elimination and others, one valve can be used as multiple valves to save the total equipment investment.

Beautiful appearance: The innovative structure of the top of the control device is adopted, small appearance space, simple internal structure, and strong reliable operation.

Easy maintenance: The open and close of the valve is driven by the conveyed medium, and it is interlocked with the water pump automatically,which is very convenient without personnel and external force to operate.

Slow opening of the pump: after start the pump, the valve inlet pressure reaches the predetermined value before the valve opens, the valve can open, which can reduce the current of starting the pump and ensure the safety of the motor and electric control system.

It is closed quickly and then closed slowly when the pump is stopped,it eliminates water hammer effectively and ensures the system security.

The closure parts are oblique butterfly disc type, the water flow is smooth, and the pressure loss and local loss are very small.

Reliable sealing, zero leakage: soft and metal double sealing structure or metal seated structure, small fiction torque of sealing pair; The oblique eccentric structure seals the pair, shortens the stroke of the closing valve, reduces the slipping distance of the sealing ring, reduces the fiction torque, achieves the effect of instantaneous clutch, and has the functions of anti-sediment and automatic pressure compensation.

Simple maintenance: no connecting with external power and components, few fault points, and the maintenance of parts in the hydraulic cylinder can be carried out at the same time as the normal operation of the unit. The key parts are made of high-quality materials, which are basically maintenance-free, and the filter in the external control pipeline has a self-flushing function.

Adopt butterfly structure, with the characteristics of small volume, light weight, small space, reduce the civil construction cost. The electro-hydraulic control system of the liquid control check butterfly valve is cancelled, which reduces the cost and increases the reliability and stability, and reduces the power consumption to achieve the purpose of energy saving.

When the nominal diameter is> DN300, the relevant valve buffer piston damping protection device is set up to protect the sealing surface of the valve effectively and reduce the vibration and sound of the closing valve.
