Norriseal Series 8760P and 8760E Valve Controllers (Positioners)

Norriseal Series 8760P and 8760E Valve Controllers (Positioners)

Series 8760 Valve Controllers (Positioners) provide an intelligent approach to valve control applications. The product series is modular in concept, built on the base pneumatic unit, the Series 8760P. The Electro-Pneumatic model, Series 8760E, is created by adapting an I/P transducer to the base unit.

The Series 8760P is designed to provide a universal approach to valve control. The design provides cam characterization, split ranging, direct or reverse action and single or double output without the need to add additional parts. Key features of the design are the non-interaction of the zero and span adjustments, and the positive cam locking mechanism. This turns calibration of the Models 8760P and 8760E into two easy steps.

All models of the Series 8760 valve controllers have provisions for mounting of internal limit switches as well as position feedback devices without the need for additional housings. Stacking of housings that impede access to adjustments in the main enclosure are eliminated.

Features

  • Flush-mounted internals and open design allow easy access and repair
  • Removable door
  • Easy, field-reversible action
  • Significantly reduced leak paths minimize bleeding of valuable gases
  • NACE MR0175-2002 compliance with optional diaphragm seals to isolate the sensing element
  • Optional instrument air regulator
