Type 2422 valve - balanced by a bellows, PN16
Type 42-24 differential pressure regulator, DN15–250, consisting of valve and closing actuator.
Application
Differential pressure regulator (differential pressure control).
For use with water and other liquids; stem; oils; air and non-flammable gases; heat transfer oil.
Particularly suitable for district heating supply networks
Description
Type 42-24 differential pressure regulator, DN15–250.
Features and benefits:
- Consisting of valve and closing actuator - valve closes when the differential pressure rises.
- Set point adjustable in wide range.
- Low-noise, medium-controlled proportional regulator requiring little maintenance.
- Suitable for circuit water, water/ glycol mixtures, steam and air as well as other liquids, gases and vapours, provided these do not affect the characteristics of the operating diaphragm.
- Valve body optionally available in cast iron, spheroidal graphite iron, cast steel, cast stainless steel or forged stainless steel.
- Single-seated valve with a plug balanced by a stainless steel bellows or a diaphragm (DN65 to DN250).
- Particularly suitable for district heating supply networks.
