 One. Overview: 

 YQ98009 filter set than the valve piston is one of the company's newly developed products, a national initiative. The valve is the use of import, export area of pressure difference, the use of inlet and outlet pressure of the force suffered under different circumstances to achieve a balance, so that inlet and outlet pressure ratio constant as the pressure ratio. So as to achieve the purpose of setting than the decompression. 

 The valve is widely used in water, fire and industrial and mining pipe water system, water supply system is a system for the protection of safe water from the branch of essential equipment. 

 II. Features: 

 1. The valve structure is simple, accurate and easy to scale to achieve a large proportion of decompression. For example: 4:1,5:1 
 2. The valve sensor is not in the flow channel into the piston, to overcome the past, because similar Valve sand, welding slag, etc. stuck, causing failure problems. 
 3. For a variety of pressure ratio options: 1.5,2,2.5,3,4,5 
 4. Y-shaped raft of wide-body cavity, small flow resistance, strong anti-cavitation, no noise. 
 5. Own filter and shockproof pressure gauge, so that bar size reduced by about 40% less space, reduce investment costs. 
 6. Stable and reliable operation can reduce the dynamic pressure, static pressure can be reduced further. 
 7. Internal and external surfaces are sprayed green coating, ensure anti-corrosion and to ensure product safety 

 If used in sea water indicate when ordering
