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 requiring precise pressure control, such as heating, sterilization, and manufacturing, where maintaining a set pressure between 3 psi and 20 psi is critical.

What are the specifications of the SPENCE E-C1H9A1B1AH1 pressure regulator?

The SPENCE E-C1H9A1B1AH1 is a 2 in x 2 in NPT x NPT pilot-operated pressure regulator with a cast iron body. It has a pressure range of 3 psi to 20 psi and a maximum temperature of 450 °F. It is designed for general purpose pressure regulation in industrial applications.

Where to buy a SPENCE pressure regulator worldwide?

3G Electric supplies the SPENCE E-C1H9A1B1AH1 pressure regulator to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for a quote and lead time on this cast iron, 2 in NPT regulator with a 3 psi to 20 psi range.

How to install a SPENCE pilot-operated pressure regulator?

Install the SPENCE regulator in a horizontal pipeline with the arrow on the body matching flow direction. Ensure upstream piping is clean and free of debris. Use a strainer upstream and a pressure gauge downstream for monitoring. Follow standard steam or gas piping best practices for safe operation.
