| Controller is fixed directly and design
of controller conduit is not needed. Controller is designed to be screw fastened quickly, enabling fast and easy installation. The valve body can match with all types of controller whitout technical conversion, and all kinds of control valves can be formed. Piston tub design is adopted for the valve body structure, making the valve applicable to low and high pressure in both vertical and horizontal positions. Straight flow path design inside the valve body. Large flow rate.Malfunctions due to water impurity or unfavorable effects from turbulence can be reduced. The valve body is shaped and formed as whole. Small volume, light weight, and easy installation. Appearance of the valve is simple and elegant. |

| The valve body of main valve becomes functional by a inlet guiding hole.This hole transfer pressure to pressure chamber. When enough pressure accumulates in the pressure chamber, it generates pushing force that makes the piston close to valve seat and generates the closing motion. There is another outlet guiding hole inside the pressure chamber. When the hole is open, pressure in pressure chamber dissipates and valve gate is pushed open by incoming water pressure. | Materials of valve
body : Cast iron, Bronze, Stainless steel Specification: JIS-10K Special order is needed for other specification. Utilization conditions: normal temperature state and other fresh fluid. Test pressure for cast iron and bronze valve body : 21 kgf/cm2 Test pressure for stainless steel valve bodyˇG 35kgf/cm2 |
