Spence MP-POS Regulators

The Spence MP-POS 760P MoorePos is a critical pneumatic positioner designed for high-performance steam and fluid control. As an external pilot operated unit, this lever-operated regulator provides a versatile 1/2 to 2-inch stroke length, ensuring precision in demanding industrial environments. For contractors managing commercial HVAC systems, the 760P model is the industry standard for maintaining stable delivery pressure under fluctuating load conditions. Its modular design allows for the integration of gauges and non-interacting zero and span adjustments, which are essential for HVAC repair and rapid field calibration. This unit is built with high-grade cast iron or steel to handle high-pressure steam applications and is NEMA 4X rated for environmental resilience. When troubleshooting steam regulators, the lever mechanism on the 760P MoorePos offers immediate mechanical feedback, allowing for visible confirmation of valve position. Proper installation of this pilot-operated pressure regulator ensures dead-end shutoff and prevents systemic hunting, making it an indispensable component for optimizing heating and cooling maintenance workflows.

• Precision Control: Features a sensitive lever-operated mechanism for accurate valve positioning within a 1/2 to 2-inch range.
• Industrial Durability: Robust construction suitable for high-temperature steam and high-vibration industrial sectors.
• Streamlined Maintenance: Includes non-interacting zero and span adjustments to simplify HVAC system calibration out in the field.
• Versatile Compatibility: Designed for seamless integration as a pneumatic positioner on a variety of Spence main valve bodies.

How do I adjust the stroke length on a Spence 760P positioner?
The stroke is adjusted via the MoorePos lever mechanism. Professional technicians must calibrate the 1/2 to 2-inch stroke by setting the non-interacting zero and span, ensuring the pneumatic signal matches the physical valve travel precisely.

What is the difference between the 760P and 760EP models?
The 760P is a strictly pneumatic positioner, whereas the 760EP includes an integral I/P transducer for electro-pneumatic control. The 760P remains preferred for steam system regulation where 3-15 psi control air is the standard.

Can this regulator handle outdoor industrial environments?
Yes, the Spence MP-POS 760P is typically housed in NEMA 4X rated enclosures, providing resistance to corrosion and moisture, which is vital for commercial HVAC units located on rooftops or in damp boiler rooms.
