ASCO 8220G402 Solenoid Valve 24V DC
The ASCO 8220G402 is a 2-way, normally closed solenoid valve designed for controlling fluid flow in compatible piping systems. It features a brass body with PTFE seals and a 3/8 inch nominal pipe size for standard connections. The unit operates on 24V DC power and uses a diaphragm and piston mechanism for reliable actuation. A Cv rating of 4.4 indicates its flow capacity under standard conditions.
Suitable Applications and Limitations
This valve suits installations requiring on/off control of air or inert gas where a normally closed configuration is specified. The brass construction and PTFE seals offer broad chemical compatibility for general-purpose use. Buyers needing control of fuel gas or fuel oil should look elsewhere, as maximum pressure differentials for those media are not applicable. Systems requiring a normally open default state or a different pipe size will require an alternative valve.
Critical Specification for Selection
The 24V DC voltage requirement is the single specification that determines whether this valve integrates with your control circuit. Supplying a different voltage will prevent operation or damage the coil. Verify that your power supply matches this exact rating before purchase. The 3/8 inch pipe size and 1/2 inch orifice must also match your plumbing layout for proper fit.

Questions about this item
How can I confirm the 24 V DC coil is energising the diaphragm-and-piston valve after installation?
Apply 24 V DC and listen for a distinct click; then verify flow through the 3/8 in brass body stops when power is removed, confirming the normally-closed action.
What components arrive with the 8220G402 valve and what must I source separately?
The valve body with 1/2 in orifice, PTFE seals and 24 V DC coil are supplied; you must provide compatible 3/8 in piping, fittings and a 24 V DC power supply.
Which 8220G402 variant should I select for a 4.4 Cv brass valve running on 24 V DC?
The listed 8220G402 is a single 2-way normally-closed version with 4.4 Cv, brass body, PTFE seals and 24 V DC coil — choose this exact model.
