Product Details
The product is designed for residential, commercial, and industrial low or high pressure boiler applications, suitable for boilers of any steaming capacity. It features Monel bellows for corrosion resistance, a float chamber with an integral water column that provides snap action for high temperature service, and includes a single pole, single throw switch for pump control along with a single pole, double throw switch for low water cut-off and alarm actuation. The kit offers optional features such as a manual reset and integral conductance probes for additional levels and greater operating differential. The model 157S-RBP-MD includes 1" or 1-1/4" NPT equalizing tapings and 1/2" or 3/4" NPT tapings for gauge glass/tri-cock installations with BSPT threads. The maximum pressure is 150 PSI (10.5 KG/CM2), and the model 157S-MD has a maximum differential operation that prevents nuisance burner shutdowns in low pressure applications operating below 50 PSI (3.5 KG/CM2). The product is made in the USA.
