Product Description
Features
Simple structure, easy installation, save investment in ultra-strong hydraulic performance, work conversion frictionless high reliability, moving parts run smoothly anti-chemical corrosion materials, suitable for a variety of media water flow rapid, high backflushing efficiency.
Standard pressure level:10 kgf/cm²
Minimum operating pressure:1.0 kgf/cm²
3"-35 square/hour, plastic bayonet
Hydraulically drive the diaphragm control valve
Unique plastic valve core assembly design, strong sealing, corrosion resistance
The valve travel is short, the flow changes smoothly and smoothly, avoiding the mixing of clean water and sewage
Valve body PA material design, corrosion resistance, acid and alkali resistance, long service life
The drive can be removed independently for easy on-line inspection and maintenance
Fully automatic backwash filtration system dedicated hydraulic control valve, driven by the pressure of the pipeline system, can automatically carry out two-way switching, to achieve automatic backwash filter. The simple structure and high reliability ensure long-term, stable operation without maintenance. The diaphragm drive structure requires only a short stroke to smoothly change the flow of water, close the inlet when the backwash port is open, and vice versa. Avoid filter over flows or water mixing with wastewater.
Take the straight-through flow control valve as an example: when the policy filters the working state, the inlet and outlet are connected, and the water flow is moving forward. When the external pressure water [1]into the diaphragm control cavity[2], pressure increases,diaphragm [3] drive valve core assembly [4] up into the upper seat[5] , the inlet is closed strictly, at this time the sewage outlet and the outlet, the water flow back from the outlet to the sewage outlet into the backwash state. When the water in the control cavity is discharged, the pipe water pressure and spring elasticity[6] work together to bring the valve core [4]assembly back to the lower seat[7] of the sewage outlet, the sewage outlet is closed and strict, and the control valve returs to the filter mode.
