Safety Valves Flanged End & Screwed
Safety valves are critical components in pressure systems, designed to automatically release excess pressure to prevent equipment failure or accidents. These valves are essential for maintaining safe operating conditions in boilers, pipelines, and pressure vessels by opening when system pressure exceeds the preset limit.

Available in both flanged and screwed (threaded) end connections, these valves cater to various installation needs. The flanged end is typically used for high-pressure or industrial applications, offering a secure and reliable seal, while the screwed end provides a more compact and easy-to-install option for smaller or lower-pressure systems.
- Size Range: 1/2" (15mm) to 12" (300mm)

- PN10, PN16, PN25, PN40 (Flanged)
- Class 150, Class 300, Class 600 (ANSI Flanged)
- BSP/NPT threads (Screwed)
- Temperature Range: -20°F to 750°F (-29°C to 400°C), depending on material
- Body Materials: Cast iron, carbon steel, stainless steel (304, 316), or bronze
- Seat Materials: Metal (hardened steel, stainless steel) or soft seats (PTFE, Viton)
- Spring Material: Stainless steel or Inconel, depending on temperature and pressure requirements
- End Connections:
- Flanged (ANSI or DIN standards)
- Screwed (BSP, NPT)
- Relief Set Pressure: Adjustable according to the specific application requirements
- Operation Type: Direct spring-loaded or pilot-operated
- Overpressure Protection: Automatically releases pressure when the system exceeds the set limit, ensuring safety and preventing potential damage or accidents.
- Flanged or Screwed End Connections: Available in both options to suit diverse installation needs, with flanged connections offering robustness for higher-pressure systems and screwed ends for compact, lower-pressure setups.
- Wide Range of Pressure and Temperature Ratings: Accommodates different industrial environments, from high-pressure steam applications to lower-pressure air and gas systems.
- Corrosion-Resistant Materials: Available in stainless steel, carbon steel, and other durable materials for reliable performance in harsh conditions, including corrosive and high-temperature environments.
- Adjustable Set Pressure: Can be fine-tuned according to system requirements, ensuring precise and safe pressure control.
- Bubble-Tight Sealing (Soft Seat Models): Ensures leak-free performance, particularly for gas or air systems, with PTFE or Viton seats for chemical compatibility.
- Compact Design: The screwed-end models are designed for easy installation in space-constrained environments, ideal for smaller systems or where maintenance access is limited.
- High-Capacity Discharge: Designed to release large volumes of fluid quickly, preventing dangerous pressure build-up in sensitive systems.
- Easy Maintenance: Replaceable seat and disc components allow for quick and easy servicing, reducing downtime.
- Compliance with International Standards: Manufactured to meet or exceed industry standards such as ASME, API, or DIN, ensuring safety and reliability in critical applications.
