SK710X Electromagnetic Control Valve is a diaphragm type of hydraulic control valve driven by the hydraulic pressure within the piping system. This type of valve is widely applied in the field of piping system optimization, pressure division, water reservoir (tank) backup, change of industrial valves, etc., with its closing and opening remotely controlled by electric signal.

◔Operational principle

SK710X Electromagnetic Control Valve is controlled by solenoid valve and equipped with normally open (or normally closed) two positions two ways or two positions three ways solenoid pilot valve, needle valve, mini strainer and ball valve, etc.

When the normally open solenoid valve is applied, the main valve in most cases will be in open position. When there is pressure coming from the flow direction, Pressure P1 enters the upper cavity room of the valve through the guide tube and then comes to the low pressure area through the normally open solenoid valve. In this way the upper cavity room is not able to form confined space and the disc of the main valve will be opened at the pressure of P1. When the normally open solenoid valve is closed, pressure P1 will be accumulated inside the upper cavity which will gradually push the membrane to close the disc and the valve.

For normally closed solenoid valve, the main valve will be in most cases closed and operation principle same as stated above. The application of the solenoid valve depends on the working environment. In case the water inside the piping system are highly corrosive or with high deposits, user can choose also to control the valve with medium from outside. It's up to the option of the client, depending on different working conditions.

◔ Property and advantages

• Driven by pressure of pipe system, work automatically with energy of pipe system to achieve energy conservation and environment protection.

• Controlled by the pilot valve, lower energy consumption, achieve accurate pressure reducing results, have function of stabilizing pressure after the valve.

• Dual cavity design, with functions of fully opening and fully closing. Slow shut causes no pressure fluctuation, and the diaphragm with support is well protected.

• Have internal orifice, connect bottom cavity and outlet of the basic valve, make sure stability of reaction to keep stability of pressure after the valve, avoid any vibration and noise.

• Channel with straight-flow, slight friction loss, no eddy flow and turbulent flow, cut down the damage of cavitation.

• Long pitch orientation design for stem move, stable and no gap resistance.

• Balanced automatically, big gap design on connection of disc and stem, disc is free on the vertical flat against stem, it can balance the tolerance from machining and sealing surface. Good connection without leakage. Achieve functions of both reducing dynamic pressure and reducing static pressure.

• Ductile iron castings with nodularity higher than 90%, foundry in house with advanced melting technology and strict quality control system, testing reports and testing bars can be supplied with order. Records and testing bars maintained for one year in the factory.

• Good corrosion resistance, with stainless steel, copper alloy, rubber made from DuPont and other rust- resisting material, fusion bonded epoxy coating both for interior and exterior surface of the basic valve. All the characteristics in accordance with ANSI/AWWA C550 and other international specifications like WRAS, NSF61.
