CONCOA 429 Series Regulator

The Kunkle Bailey 616D safety relief valve is a spring-operated, high-capacity safety valve specifically designed for low-pressure air applications.

Commonly utilised on blowers or bulk transfer vehicles for road and rail transport, the Kunkle Bailey 616D safety relief valve offers essential overpressure protection for positive displacement air blowers, as well as associated tanks and pressure vessels.

Features:

• Engineered to provide precise relieving and re-seating pressures.
• Protected open discharge facilitates downward flow.
• Non-stick seating surfaces ensure a positive shut-off and prevent sticking.
• A combination of aluminium and gunmetal offers a lightweight yet extremely robust construction.

Specifications:

• Material: Body - Aluminium / Trim - PTFE & Bronze
• Sizes: 1.1/2" to 2" (DN40 to DN50)
• Connections: BSP Female inlet x Open discharge outlet
• Medium: Air
• Pressure Range: 0.2 to 2.5 barg (2.9 to 36.3 psig)
• Temperature Range: -30°C to 200°C

The Kunkle Bailey 616D safety relief valve is the ideal solution for maintaining safety and efficiency in your low-pressure air systems, ensuring reliable performance in various applications.

Introducing the FSSCRRA Reverse Acting Rupture Discs – advanced compression or reverse discs featuring micro-scored calibrated sections that open in the form of petals. These discs are designed with 4, 6, or more radial scores, allowing for optimal opening and significantly reducing the risk of petal detachment. The FSSCRRA rupture discs are ideally suited for both high and low bursting pressures and can be safely utilised with gases and liquids (when a special gas cushion is present), even under cycling and pulsating conditions, without compromising safety margins. Reacting to excessive pressure within mere milliseconds, FSSCRRA rupture discs operate without fragmentation, making them particularly effective for the protection of safety valves. These rupture discs boast an impressive operating to bursting pressure ratio of up to 95% and demonstrate excellent corrosion resistance. This resistance can be further enhanced with a PTFE lining. Notably, FSSCRRA discs can operate under absolute vacuum conditions without requiring additional supports.

The Medenus RS255 Gas Pressure Regulator and Shut Off Valve guarantees a consistent outlet pressure, irrespective of the primary inlet pressure. This device adeptly manages variations in gas usage, providing rapid pressure regulation when there are sudden changes in flow rate. Additionally, the integrated safety shut off valve ensures secure operation by shutting off in the event of excessively high or low pressure levels.

The Medenus RS255 Gas Pressure Regulator and Shut Off Valve complies with DVGW Code of Practice G260/262 and is suitable for all neutral and non-corrosive gases (other gases available upon request). It comes with flange connections ranging from DN50 to DN100 and is capable of handling working pressures up to 16 bar. All gas pressure regulators in this range are certified by DVGW and carry CE certification.

Every regulator in the RS series boasts several options, including a safety membrane, vent valve, remote release for the shut off valve (SSV), noise reduction features, and more. For comprehensive details, please consult our documentation or reach out to our team.
