Spence E2-2 Valve

The Spence E2-2 is a heavy-duty 2 inch cast iron main valve engineered for precision fluid and steam pressure regulation. As a pilot-operated normally closed valve, the E2 series is the industry standard for contractors managing large-scale district heating or industrial steam plants. This Spence E2-Main Valve CI features a single-seat design and packless construction to reduce friction and eliminate the need for traditional stuffing box maintenance. With a maximum rating of 15 PSIG at 250°F, it provides ANSI/FCI 70-3 Class IV shutoff reliability, ensuring tight closure on dead-end service. The unit is built with stainless steel trim and a high-durability Hycar diaphragm, making it compatible with a wide range of pilots, including the Type D for pressure reduction and the Type T14 for temperature control. Designed for horizontal piping runs, this 2" E2 main valve utilizes a protected main spring and internal bleed port mechanics to deliver consistent downstream pressure regardless of inlet fluctuations.

• Frictionless Operation: The packless design with stainless steel trim minimizes mechanical wear for long-term reliability in specialized HVACR applications.
• High Flow Capacity: The 2-inch full port orifice is optimized for maximum Cv ratings to handle demanding steam loads without excessive pressure drop.
• Versatile Compatibility: Seamlessly integrates with Spence D, T, or Q series pilots to function as a steam pressure reducing valve or temperature regulator.
• Tight Shutoff: Engineered to meet Class IV shutoff standards, preventing "steam creep" during periods of low demand or system idle.
• Rugged Construction: The cast iron body is designed to withstand the thermal stresses found in low-pressure steam heating systems.

What is the maximum pressure rating for the Spence E2-2?
The standard cast iron E2-2 is rated for a maximum inlet pressure of 15 PSIG and temperatures up to 250°F, specifically targeting low-pressure steam service.

Can I install this valve in a vertical pipe run?
For optimal performance and drainage, this main valve should be installed in a horizontal run of pipe with the diaphragm chamber facing down to prevent condensate buildup.

Which pilot regulators are compatible with the E2-2?
As a veteran technician knows, the E2 is a universal main valve that can be paired with any Spence pilot, such as the D series for pressure reduction or the T14 for combined temperature and pressure management.
