Features

• Use C437 for SPST (non-mercury) switching.
• Models intended for lockout applications must be manually reset before resuming operation.
• Compensate for momentary surges in gas pressure with a restrictive orifice in inlet pressure channel on the models with pressure range of 1 to 26 in. wc (0.25 to 6.5 kPa).
• Impede tampering and provide dust-resistant operation with enclosed setting.
• Increase strength of control diaphragm with Buna-N fiber-reinforced material.
• Two Buna-N fiber-reinforced seal-off diaphragms for added reliability.
• Clear glass cover allows observation of interior mechanism to aid in setting and checkout.
