Solenoid Valve

Solenoid Valve
2-Way Solenoid Valve Poppet Type - N/C

WHAT IS IT? This is a two-way, two-position, normally closed, poppet type Solenoid Valve. It has an anodized aluminum Body and all ferro-magnetic materials in the Solenoid Assembly are electroless nickel plated for corrosion protection. The Solenoid is threaded into the Body and secured with a locking type Set Screw. The Electrical Connector is a two-pin type per MS-3102A-12S-3P. The Valve has pressure
Solenoid Valve
ratings of 800 psig operating, 1000 psig proof and 1500 psig burst. It will withstand and operate under 10 G's Loading along any axis. The Solenoid operates normally with 24 to 30 VDC and draws a maximum of .75 amps at 75 degrees F ambient temperature.

HOW DOES IT WORK? The Valve is spring and pressure-aided closed. By applying 24 to 30
VDC to the Coil, the Armature, which contains an elastomeric Poppet, is actuated against the spring, opening the fluid path. Opening or closing response is less than 30 ms. The Solenoid is rated for continuous duty and the Valve has a minimum service life of 100,000 cycles. This unit is designed to have very minimal internal leakage. There is no evidence of fluid leakage in 15 minutes with 800 psig applied to the inlet port and the outlet vented to atmosphere. Flow is the equivalent of a sharp-edge orifice of .060 diameter where Cd is .65.

HOW IS IT USED? Materials are compatible with aviation gasoline, kerosene, JP-4, JP-5 and alcohol. The system has a temperature tolerance range from -65 degrees to +165 degrees F. The Valve has application in air, fuel and liquid cooling systems. With alternate elastomeric seals and poppet materials, it is also compatible with standard and synthetic hydraulic fluids. The unit is small and light-weight at 7 ounces. The unit pictured is used as a fuel tank transfer valve and fuel line blowdown valve on several small business aircraft.

Hi,
Thanks for the great details about various types of valves, i really looking out for this kind of information.

We are leading manufacturers of Solenoid Valves, Check Valves, Expansion Bellows, etc.
