Typical applications

  • Petrochemical industry temperature control
  • Metallurgy temperature control
  • Chemical engineering temperature control
  • Energy sector temperature control
  • Papermaking industry temperature control
  • Light industry temperature control
  • Urban centralised heating systems
  • Heating systems

Actuation options

Self-operated (medium temperature as power source)

Features

  • No external driving energy required; medium temperature serves as power source
  • Stainless steel bellows pressure-balance plug reduces force on plug under differential pressure
  • O-ring sealed valve stem with reduced friction compared to packing seal
  • Heating type (temperature-closed) and cooling type (temperature-open) temperature controllers are interchangeable
  • Gas-bag type over-temperature protection structure permits over-temperature of 100°C
  • Independent instrument control system integrating detection, control, and execution functions

Description

A self-operated temperature control valve that uses the temperature of the regulated medium as its sole power source, requiring no external driving energy. It integrates detection, control, and execution functions into a single valve body, forming an independent instrument control system. Available in heating type (temperature-closed) and cooling type (temperature-open) configurations for non-corrosive liquids, gases, and steam.

Selection notes

This control valve is a self-operated temperature regulator and self-operated pattern.

Sizes run DN15 to DN125, in PN16, PN25, PN40.

The body is offered in WCB, WCC, LCB and LCC, so the grade can be matched to the service rather than the other way round.

Stated service media include non-corrosive liquids, gases, steam and vapours.

It is catalogued for HVAC.

Working temperature is 80°C to 350°C.

Self-operated Series configurations

View full Self-operated Series system →
This product is part of the Self-operated Series modular system. All configurations share the same hydraulically operated body: the control function is set by the pilot valve(s) attached. An existing Self-operated Series body in the field can be reconfigured for a different duty simply by swapping the pilot, without replacing the body.
