The Suction Control Valve includes a fuel cooled solenoid valve. The SCV is changed by a solenoid coil that modulates the pulse width at 1 KHz.

When the SCV is not activated, the internal spring will maintain a fuel pressure of about 100 Bar. When the SCV is activated, the electromagnetic force assists the spring, reducing the valve's opening and increasing fuel pressure. SCV is also used as a mechanical pressure damper to smooth the high frequency pressure pulse from the radial piston pump when less than three pistons are activated.

Ningbo HENSHINE Precision Machinery Co., Ltd. is a factory that focuses on SCV fuel control valve and high pressure common rail control valve and manufacture of solenoid valve products.

 Which are widely applied for vehicles such as suction control valve , fuel inlet metering valve, inlet metering valve and pressure limiter valve in diesel common rail system.
