Normally-open, single-seated pneumatic radiator valve with
straight through or angle body construction provides proportional
control of two-pipe, hot water or steam systems. Replacement
devices are available for Johnson, Powers, Robertshaw, Barber-
Colman, and older Honeywell devices.
• Available in several capacities and spring ranges for various
application requirements.
• Easily replaceable actuator assembly for convenience of service.
• Compact size for installation where space is limited.
• Can be repacked without shutting down system.
