Frequently Asked Questions

What is the SPENCE SPS-30 pressure pilot regulator used for?

The SPENCE SPS-30 is a cast iron pressure pilot regulator used in steam, air, and gas systems to maintain a set downstream pressure. It is commonly applied in industrial process control, heating systems, and plant utility lines where precise pressure regulation up to 30 psi and 450°F is required.

What are the specifications of the SPENCE SPS-30 pressure pilot regulator?

The SPENCE SPS-30 has 1/4 in NPT inlet and outlet connections, a cast iron body, and a pressure range of 2 psi to 30 psi. It is rated for maximum operating temperature of 450°F. The manufacturer part number is SPS-30, and it is designed for general-purpose pressure regulation in industrial applications.

Where to buy the SPENCE SPS-30 pressure pilot regulator worldwide?

You can source the SPENCE SPS-30 pressure pilot regulator through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations.
