The Cla-Val Model 50B-4KG1 (globe) and 2050B-4KG1 (angle) is designed specifically to relieve excess pressure in fire protection systems. This pilot-controlled valve keeps system pressure at the pump discharge within close limits as demand changes. It opens fast and closes slowly, protecting the system against high pressure surges on pump start-up and shut-down by discharging excess pressure to a safe location.
Key features
- Globe and angle patterns
- Fully automatic operation with easily adjustable pressure setting
- Fast opening, slow closing action against surges
- Replaceable 316 stainless steel seat and dual guided stem
- Can serve pressure relief, pressure sustaining, back pressure or unloading functions
Typical applications
Main relief valve on diesel and electric fire pump discharge, discharging through a waste cone, and pressure sustaining duties in fire protection bypass systems.

Applications in Fire Protection Systems
The Cla-Val 50B-4KG1 and 2050B-4KG1 pilot-controlled relief valves are engineered specifically for fire protection systems that require precise pressure management. These valves serve as the main relief valve on diesel and electric fire pump discharges, effectively discharging excess pressure through a waste cone. They are also utilized for pressure sustaining duties within fire protection bypass systems. By maintaining constant pressure at the pump discharge, these units protect critical infrastructure against high pressure surges that occur during pump start-up and shut-down cycles. This makes them suitable for various building types where reliable, automatic pressure regulation is essential for the integrity of water-based fire suppression networks.
Key Technical Features
- Available in both globe and angle patterns to suit different installation requirements.
- Fully automatic operation featuring an easily adjustable pressure setting.
- Fast opening and slow closing action designed to mitigate pressure surges.
- Constructed with a replaceable 316 stainless steel seat and a dual guided stem.
- Versatile functionality that can serve as pressure relief, pressure sustaining, back pressure, or unloading valves.
- Automatically relieves excess pressure to keep system limits close as demand changes.
