brass control valves
Pressure independent control valves for hydronic systems. The body is made of dezincification-resistant brass. The internal pressure controller is made of high temperature engineered polymer for prolonged service life. Close-off pressure rating of 232 PSI. Linear valve characteristic, modified by the actuator characteristic. Lockable setting. Flow setting range. Field adjustable. Easily visible flow setting dial. The flow rate can be adjusted without removing the actuator or decommissioning the valve. The flow setting of the valve is indicated in GPM. No conversion chart is necessary.
