Valve configuration and application

The Red Hat 8221G007 is a 2-way, 2-position pilot-operated solenoid valve with a normally closed design. It controls the flow of water in plumbing systems and arrives new with the operating coil and seals included. The valve suits installations that require automatic on-off fluid control at a 1 inch nominal pipe size.

Pressure differential range

This valve requires a minimum pressure differential of 5 psi to open and handles a maximum operating pressure differential of 150 psi for water and hot water. The brass body and NBR seals manage the fluid passage within these limits. Select this model only when the system pressure stays inside the 5 to 150 psi window.

Sustained operation characteristics

The coil insulation class F and IP66-rated enclosure protect the 120V AC, 6.1 W coil during continuous energised periods. Maximum fluid temperature is rated at 180°F for extended service. The slow-closing, pilot-operated action reduces water hammer during repeated cycling under load.

Questions about this item

What does the Cv of 3 mean for water flow through this valve?

A Cv of 3 indicates the valve will pass approximately three US gallons per minute of water with a one psi pressure drop across the valve.

How does the NPT connection and 150 psi limit affect installation?

The 1 inch NPT threads seal with tape or paste, and the valve is rated for a maximum operating pressure differential of 150 psi for water and hot water.

What are the overall dimensions and centre-line size for mounting this valve?

The valve measures 3-3/4 in overall length, 3-3/16 in width, 5-5/8 in height, and has a 4 in centre line pipe centre size.
