Frequently Asked Questions

What is a SPENCE pilot-operated pressure regulator used for?

A SPENCE pilot-operated pressure regulator reduces and stabilizes downstream pressure in steam, air, or gas systems. It is used in industrial processes like heating, sterilization, and pressure control across plants requiring precise regulation from 20 psi to 150 psi.

What are the specifications of the SPENCE E-C1D9A1B1AN1 pressure regulator?

The SPENCE E-C1D9A1B1AN1 is a 3/4 in x 3/4 in NPT x NPT pilot-operated pressure regulator with a cast iron body. It has a set pressure range of 20 psi to 150 psi and is designed for general-purpose industrial applications.

Where to buy a SPENCE pilot-operated pressure regulator worldwide?
