ASCO 8290A020 RedHat Piston Valve

The ASCO 8290A020 is a bronze angle body piston valve with a 1 1/2 inch nominal pipe size and orifice diameter. It is designed for 2-way, 2-position control in indoor or outdoor installations. The normally closed configuration suits systems requiring automatic shut-off when de-energised.

Thermals noise and power

The valve handles a maximum fluid temperature of 366 Degrees F across steam and water service. Operating pressure differentials reach 60 psi for both media with a minimum of 0 psi. A Cv of 52 indicates high flow capacity with minimal restriction.

FKM seal bronze body

The bronze body and FKM seals provide compatibility with steam and water up to the rated limits. No electrical coil voltage or actuation method is specified in the data. Buyers needing a specific voltage, alternate seal material or normally open operation must verify those details separately.

Questions about this item

How do I install the ASCO 8290A020 piston valve and which step is most often missed?

Thread the 1 1/2 in bronze angle body into the piping, apply sealant to the NPT connections, wire the coil for normally closed operation, then pressurise slowly — the step most often missed is verifying the FKM seals seat fully before applying full 60 psi differential.

What maintenance or replacement will the ASCO 8290A020 need over time?

Inspect the FKM seals and piston surface annually; replace the seal kit if leakage appears or after the valve has cycled near its 366 °F fluid temperature limit for extended periods.

What is the first limit reached on the ASCO 8290A020 during sustained steam or water service?

The 60 psi maximum operating pressure differential is reached before the 366 °F temperature ceiling, so pressure rating governs continuous duty.
