Learn How To Trouble Shoot A Spence Pressure Reducing Valve. Tips and Tricks to allow you to trouble shoot your Spence Pressure Reducing Valve.
The Spence Type E Main Valve is of normally closed, single seat design featuring packless construction, balanced metal diaphragms and protected main spring. When controlled by one or more of the various types of Spence Pilots, this valve will accomplish most functions required of a regulator. CAST IRON RATINGS (Maximum Inlet Conditions) Technologies; Maintenance; Think First, Then Troubleshoot — Chapter 11: Pressure-reducing Valves. Pressure-reducing valves are normally open, 2-way valves that allow system pressure fluid to flow through them until a set pressure is reached downstream. Item # 4NU80. Mfr. Model # SPS-30.

In their presentation at the Valve Repair Council Repair Meeting & Exhibition, Nov. 1 and 2, 2012, in Houston, Bob Donalson and Kevin Simmons of Pentair Valves & Controls shared valuable information about maintenance and repair programs for pressure-relief valves. After covering the various types and functions of PRVs and defining their physical characteristics, Donalson and Simmons discussed Spence T124 complete temperature pilot with a temperature range of 120-220°F and a 10' capillary length. This pilot is for use with "E" series main valves.
