Spence BF-2 1/2-KIT Valve

The Spence BF-2 1/2-KIT is a specialized bends and fittings assembly designed specifically for the 2-1/2 inch Spence Type E Main Valve and E2-Valve series. As a veteran technician knows, the integrity of the pilot-to-main-valve connection is critical for maintaining precise pressure regulation and preventing hunting or erratic discharge. This steam pressure regulator kit provides the exact replacement delivery tubing and orifice fittings required to restore the communication link between the pilot diaphragm and the main valve body. Constructed for high-demand HVAC steam system maintenance, these components handle the rapid pressure differentials common in commercial and industrial piping. By ensuring the bleed port and restriction elbow are clear and properly seated, this kit eliminates common failure points like plugged orifices that cause the valve to fail closed. Rely on these Spence valve repair parts for a factory-spec fit that maintains the packless, single-seat performance of your 2-1/2" E-Valve without the risk of sub-standard field-bent alternatives.

• Ensures accurate pilot-to-diaphragm pressure signaling for optimal steam valve regulation.
• Includes the critical restriction elbow and bleed port fittings to prevent valve hunting.
• engineered for the 2-1/2" Type E series to maintain ASME-rated boiler system integrity.
• Reduces downtime by providing pre-formed bends that eliminate field-fabrication errors.
• Supports consistent dead-end shutoff performance in steam and fluid control applications.

When should I replace the bends and fittings on my Spence E-Valve?

Replacement is necessary if the delivery tubing is kinked, corroded, or if the internal orifice fittings have become scale-clogged, preventing the pilot from stroking the main valve open or closed.

Will this kit fix a valve that is leaking from the bleed port?

The Spence BF-2 1/2-KIT ensures the bleed port is properly sized; however, continuous steam leakage usually indicates a worn pilot seat or a ruptured main valve diaphragm rather than a fitting failure.

Is the kit compatible with both Cast Iron and Steel Spence valves?

Yes, this kit is designed to fit the 2-1/2" Type E geometry across standard body materials, provided the piping configuration is a standard pilot-operated setup.
