Butterfly Valve Assembly, 2-Way, 8", Full Cut Disc, Electric NSR, Modulating 0-10 Volts DC, 120 Volts AC, Lug, Heater

This 2-Way Butterfly Valve Assembly features a 8" Valve with a Heater and an Electric NSR Actuator with Modulating 0-10 Volts DC and 120 Volts AC Control. Features of the 150 psi Close-Off Assembly include a molded resilient seat and a lugged body style which is drilled and tapped for isolation and removal of downstream piping. Each valve is factory tested to 100 percent of specified pressure rating.

Pentair Valves & Controls combines over 50 years experience and knowledge in the valve and actuator industry with Siemens Building Technologies’ expertise and recognition in HVAC/building automation systems to provide the ultimate automated butterfly valve assemblies for flow control of:

• Hot water
• Chilled water
• Condenser water
• Thermal storage systems
• Steam

Features Include:

• Actuator choices: Pneumatic 20 or 60 psi; Electronic (w/and w/o spring return): 0-10 V, 4-20 mA, and 2 position.
• Available for delivery in two weeks or less.
• Bronze bearings ensure longer service life with low operating torques.
• Bubble-tight shutoff to 150 psi.
• Competitively priced.
• Each valve is factory tested to 110% of specified pressure rating.
• Extended neck allows adequate clearance for flanges and insulation.
• High close-off pressures.
• Integral cast-in top plate is standardized to allow direct mounting of actuators.
• Round, polished disc and hub edge provides 360 degree concentric seating and minimizes flow restriction for longer seat life.
• Simple to configure and order.

Features and Benefits:

• Molded-in resilient seat provides bubbletight shutoff to 250 psi.
• Offered in two body styles: wafer and lug. The lugged body is drilled and tapped for isolation and removal of downstream piping at full rated pressure.
• Round, polished disc and hub edge provides 360 degree concentric seating, minimum flow restriction, lower torques and longer seat life.
• Upper and lower inboard bronze bearings ensure longer service life with low operating torques.
• Thru-stem design provides high strength and positive disc control with standardized end connection for operator interchangeability.
• Extended neck allows adequate clearance for flanges and insulation.
• Bi-directional, self-adjusting stem seal, located in the upper journal, is suitable for vacuum and pressure while also preventing external contamination of the stem area.
• Heavy-duty corrosion resistant top bushing, located in the upper journal, absorbs actuator side thrust.
• Cast-in top plate is an integral part of the body and is standardized to allow direct mounting of all Keystone actuators.
• Each valve is factory tested to 110 percent of specified pressure rating.
• Temperature rating for standard EPDM: -40°F -250°F.
• Flange standard is ANSI 125/150
