Pneumatic SPDT Relay (switching between 3-7 psi)

Pneumatic switching relays block, divert, or bleed pneumatic air lines when pilot pressure is changed from one specific value to another. Commonly applied in Day-Night, Summer-Winter, Start-Stop, On-Off-Auto and other multiple condition systems where control sequence is changed as conditions change. Replacement devices are available for Johnson, Powers, Robertshaw, Barber-Colman, and older Honeywell devices.

Features

• Available with either single-pole, double-throw (SPDT) or double-pole, double-throw (DPDT) switching action.
• Second switch on dpdt (RP670B) models molded in natural color for identification.
• Air connections for 5/32 in. (4 mm) O.D. plastic tubing.
• Molded plastic construction with neoprene diaphragms, stainless steel lever.
• In-line mounting, or wall or panel mounting with provided metal spring clip.
