Red Hat 8290A021 Angle Body Piston Valve Bronze NC 1.5 In
Bronze angle-body piston valve, normally closed, handles air, inert gases, light slurries, oil and water up to 120 psi differential with a 1.5 in orifice and 52.0 Cv
- TypeDrain Components
- Bronze body resists corrosion in water and steam systems
- Normally closed design stops flow until energised for safety
- 120 psi pressure rating handles demanding fluid control
- 0 Cv coefficient delivers high flow capacity
- 5 inch orifice matches standard piping dimensions
Angle Body Piston Valve 1.5 Inch
The Red Hat 8290A021 is a bronze angle body piston valve designed for fluid control in plumbing and industrial systems. It operates as a 2-way, 2-position normally closed valve suitable for air, inert gases, light slurries, oil, and water. The 1.5 inch pipe size and orifice diameter match standard fittings for this flow capacity. Buyers needing a smaller port or a different body material cannot use this model.
Sustained Pressure Handling
The valve handles a maximum operating pressure differential of 120 psi for both water and steam service. A minimum operating pressure differential of 0 psi allows opening without upstream pressure. The bronze body and PTFE seals maintain integrity under continuous exposure to the listed media. Installations requiring pressure ratings above 120 psi must select a different valve.
Flow Coefficient Limit
The coefficient of volume is rated at 52.0, defining the maximum flow capacity through the 1.5 inch orifice under standard test conditions. This Cv value sets the practical limit for sizing the valve in a piping system. Systems demanding a higher flow coefficient will require a larger valve or parallel installation.

Questions about this item
How much heat does the 8290A021 generate when it runs continuously with water at 120 psi?
The valve body is bronze with PTFE seals and has no electrical components, so it produces no measurable heat during continuous operation.
What piping and pressure source must I already have to install this 1.5 in angle-body valve?
You need 1.5 in NPT pipe connections and a supply capable of at least 0 psi up to 120 psi differential for water, air, inert gases, light slurries or oil.
Will the 52.0 Cv bronze valve work alongside my existing 1 in steel pipe and older pilot solenoid?
The 1.5 in orifice and 52.0 Cv flow coefficient require matching 1.5 in piping; a 1 in line would restrict flow, and the valve is pilot-operated so it needs a compatible 3-way pilot signal.
