Float Switches

Type H—Closed Tank

Class 9037 / Refer to Catalog 9034CT9701

 

Type H switches are attached to the tank by means of a 2-1/2 inch screw-in connection. An external pointer indicates the float position within the tank when the unit is mounted. Switches come complete with stainless steel float and rod. Buna N QUAD-RING® seal is used between the float rod and sealing connector. Normal application is at atmospheric pressure, but where higher pressures are encountered, the switch will withstand tank pressures up to 50 psi at temperatures up to 220oF. Occasional replacement of the QUAD-RING seal may be necessary.
