Product Description

The SPENCE Pilot-Operated Pressure Regulator is a cast iron general purpose pressure regulator with NPT x NPT connections, available in a 3/4 in x 3/4 in size and a pressure range of 20 psi to 150 psi (MPN E-C1D9A1B1AN1). 3G Electric interprets your demand for this OEM part, sourcing it across 14 industrial departments with specialist depth in combustion, pumps and controls.

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?

3G Electric supplies the SPENCE pilot-operated pressure regulator worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this model E-C1D9A1B1AN1.

How to install a SPENCE pilot-operated pressure regulator?

Install the SPENCE regulator in a horizontal pipeline with the arrow matching flow direction. Ensure upstream isolation valves and a strainer are fitted. Follow manufacturer guidelines for pilot tube connections and avoid overtightening NPT threads to prevent cracking the cast iron body.

Used in

Common applications for SPENCE
Process heating — SPENCE reverse-acting temperature regulators (e.g., 2020TD-GQD) control steam flow to maintain set temperatures in heat exchangers and jacketed vessels.
Condensate removal — SPENCE steam trap repair kit for model 4NU80 restores internal components in steam traps used for condensate removal and energy management.
Storage tank heating — SPENCE bronze temperature regulators with 1/2 in to 2 in connections modulate steam to maintain fluid temperatures in storage tanks.
HVAC and district heating — SPENCE reverse-acting regulators open on temperature drop to provide fail-safe heating in steam-based heating systems.
Industrial steam distribution — SPENCE temperature regulators and steam traps are used in steam headers and branch lines to control flow and remove condensate.
Maintenance and repair — SPENCE repair kits and replacement parts support planned maintenance programs for steam traps and regulators in continuous process plants.
