FEATURES

• Sizes from 1/2 to 3 in. with internal (female) NPT connections.
• Controls hot or chilled water with up to 50% glycol.
• Regulated flow rates available from 1 to 95 gpm.
• Differential pressure regulator for constant pressure drop across valve seat.
• Positive pressure, rolling diaphragm regulator design for flow control accuracy of ±5%.
• Equal percentage flow characteristic using patented flow control ball insert.
• Multiple maximum flow rates available per valve size.
• Patented ball seals for low operating torque.
• Nickel-chrome plated brass or stainless steel trim.
• Choice of factory-installed actuation using

Honeywell MVN or MN/MS series direct coupled

actuators: Floating, Modulating (2-10 V), Non-Spring Return and Spring Return.

• Spring return actuators field-configurable for normally open or normally closed fail-safe position.
• Removable, manual operating handle to control valve during installation or in an event of power failure.
• Upstream Test Port for venting or pressure gauge attachment.
• Three actuator orientations on the valve for cramped spaces.
