Safety Valves & Pressure relief Valves - 2252 | Genebre

Genebre 2252 Stainless Steel Safety Valve

The Genebre 2252 is an angle-type, threaded safety valve constructed from stainless steel, designed for overpressure protection in gas or steam lines. It is not intended for continuous bypass regulation but for pressure relief when the set pressure is reached.

Technical Specifications

• Connections: BSP Gas, male/female, ISO 228/1
• Sizes: Inlet 1/2" to 2", outlet 1" to 2"
• Pressure rating: PN40
• Set pressure: 0.5 to 40 bar, with tamper-proof seal
• Max operating pressure: 40 bar
• Operating temperature: -20°C to +300°C
• Body/cover: Stainless steel 1.4408 / CF8M
• Seat and disc: AISI 316
• Spring: AISI 302 up to 250°C; for higher temperatures, material verification required
• Gaskets: PTFE

Standards and Sizing

Design, calculation, and testing are in accordance with EN 12516 and EN ISO 4126-1/7. Sizing data for discharge capacity is provided for air at 20°C and saturated steam at 10% overpressure.

Applications

• Small and medium diameter steam networks
• Process gas lines
• Steam manifolds
• Thermal skids with stainless steel piping
• Equipment protection where threaded connection and stainless construction are required

Selection Criteria

Selection requires set pressure, required discharge capacity, medium, temperature, inlet/outlet size, and permissible backpressure. System operating pressure should remain sufficiently below set pressure to avoid frequent opening and seat wear.

FAQ

Is an actuator required?
No. Operation is mechanical via spring load.

Is it suitable for water?
The datasheet specifies use for gas or steam. For liquids, technical evaluation is required.

What affects seat tightness after opening?
Particles, scale, condensate, and non-draining outlets can impact seat integrity.
