What is a DEMA 453P?
The 453P is a brass piston-style valve body designed for high-pressure applications. It is sold without a coil, allowing users to select the specific voltage and connection type they need for their system.
All valves in the 453P series share common features:
Pressure range: 10 to 1200 PSI maximum differential pressure.
Body material: Brass construction.
Port size: 3/8" NPT inlet and outlet.
Operation: Pilot-piston operated.
Function: Normally closed (opens when energized).
Intended use: Water only.
What is a DEMA 453P.3?
The 453P.3 is a complete solenoid valve assembly that includes the standard 453P valve body paired with a 24VAC solenoid coil.
Key specifications for the 453P.3 include:
Voltage: 24VAC coil.
Seal: PTFE (Teflon) seal.
Operation: Normally closed.
Maximum pressure: 1200 PSI.
Body material: Brass.
Port size: 3/8" NPT connections.
