Frequently Asked Questions

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

A SPENCE pilot-operated pressure regulator reduces and stabilizes downstream steam, air, or gas pressure in industrial processes. It is commonly applied in steam distribution, heating systems, and process control where precise pressure regulation is critical for safety and efficiency.

What are the specifications of the SPENCE E-C1C9A1B1AN1 pressure regulator?

The SPENCE E-C1C9A1B1AN1 is a 1/2 in NPT x 1/2 in 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 steam, air, or gas service.

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

3G Electric supplies the SPENCE E-C1C9A1B1AN1 pilot-operated pressure regulator to customers worldwide. We handle full logistics, customs clearance, and delivery to your site, ensuring you receive the correct genuine SPENCE part for your application.

How to select the correct SPENCE pressure regulator for my system?

To select the correct SPENCE pressure regulator, verify your pipe size (1/2 in NPT), required set pressure (20 psi to 150 psi), and fluid type (steam, air, or gas). Confirm the body material (cast iron) is compatible with your system's temperature and pressure limits. Consult a qualified engineer for sizing.
