Verified by manufacturer 10 days ago
Type 45-4 - DIN
Type 45-4 - DIN
Differential pressure regulators, DN15–50.
Application
Differential pressure regulator (differential pressure control).
For use with water and other liquids, air and non-flammable gases.
- Suitable for district heating systems according to DIN 4747-1 (fulfills AGFW requirements for components in house substations).
Description
Differential pressure regulators, DN15–50.
Features and benefits:
- Consisting of valve and closing actuator; valve closes when the differential pressure rises.
- Single-seated valve with balanced plug.
- Set point adjustable between 0.1 and 4 bar.
- With set point indication (DN15 to DN32 only; set point range between 0.1 and 1 bar, or 0.1 and 0.5 bar).
- Type 45-4 includes internal overload protection (excess pressure limiter) in the actuator.
- Suitable for district heating systems according to DIN 4747-1 (fulfills AGFW requirements for components in house substations).
- With connection nuts and welding ends.
- DN15, DN20, DN25, DN32, DN 40 or DN50.
- Part of the Series 45 Self-operated regulators range.
