Spence BF-1-KIT Valve

The Spence BF-1-KIT is a complete bends and fittings kit specifically engineered for the Spence 1-inch Type E main valve. As a veteran-grade pilot-operated regulator component, this kit provides the essential tubing bends and hardware required to interface your E-Series pressure reducing valve with its pilot control system. In high-pressure steam or liquid service, the precision of these NPT fittings and pre-formed bends ensures laminar flow to the pilot diaphragm, preventing the erratic hunting or "chattering" often caused by field-fabricated lines with improper radii.

For a reliable E-Valve installation, the BF-1-KIT replaces worn or corroded original tubing, keeping your 1" Spence regulator within OEM performance specs. The kit includes the 4A bleed port fitting, which is critical for establishing the loading pressure required to actuate the main valve diaphragm. Whether you are performing a full overhaul or a spot repair on a steam pressure regulator, utilizing this application-specific kit eliminates the risk of bypass leaks and ensures the 1/8" and 1/4" tap connections are secured with industrial-grade durability.

• Direct Compatibility: Precision-fit for all Spence 1" Type E main valves, ensuring no-leak pilot connections.
• Optimized Signal Response: Pre-formed tubing bends maintain consistent internal volume for faster pilot-to-main-valve communication.
• Critical Components Included: Features the specialized bleed port fittings and elbows necessary for the normally-closed operation of the E-Series.
• Rugged Construction: Built to withstand the thermal expansion and vibration common in industrial HVACR steam systems.

Does this kit include the pilot valve itself?
No, the BF-1-KIT consists of the bends and fittings required to connect the pilot to the main valve; the pilot (such as an ED or E2 series) must be sourced separately.

Is this compatible with the 1-1/4" or 2" Type E valves?
No, this kit is specifically sized for the 1-inch E-Valve. Larger valves require specific kits (like the BF-2-KIT) due to different diaphragm chamber clearances.

Why is the bleed port fitting included in this kit so important?
The bleed port is the "brain" of the pilot system; it allows the loading pressure to exhaust, which is what enables the valve to close properly. Without this specific fitting, the regulator will not modulate correctly.
