FAQs

The EF1216B is a compact spring-loaded safety and relief valve intended for steam, gases, vapours and liquids, with threaded or flanged connection options depending on configuration. It is particularly suitable for process equipment and packaged systems where a compact flanged PSV is preferred.
The EF1216 is primarily a threaded BSP/NPT safety valve. The EF1216B provides greater connection flexibility through threaded or flanged configurations and incorporates sealing features intended to improve tightness and containment.
The EF1216B can be particularly useful where: - The equipment specification requires flanged connections - PN or ASME flange ratings are specified - Improved seat tightness is required - A sealed lifting arrangement is preferred - The valve is integrated into OEM or packaged equipment
Yes. It can be considered for thermal-expansion duties where its capacity, set pressure and configuration are suitable for the calculated relieving requirement.

ABOUT EF1216B

The Pressure Safety Valve Model 1216B is a compact, high-performance spring-loaded safety and relief valve engineered for reliable overpressure protection in pipelines, process systems, and pressure vessels across industrial applications.

Designed in accordance with EN 4126-1/7 and the European Pressure Equipment Directive (PED), the Model 1216B ensures accurate and repeatable pressure relief under demanding operating conditions. Its robust construction in stainless steel 316L and high-quality internal components provides excellent corrosion resistance and long service life.

The 1216B variant incorporates enhanced safety and operational features, including a sealed packing lever system, disc O-ring for improved tightness, and compatibility with accessories such as test gags and lifting devices. These features make it particularly suitable for applications requiring controlled emission, reduced leakage, and safer operation in sensitive environments.

With a wide operating range from -28°C to +350°C, and configurable connections including threaded (BSP/NPT) or flanged (RF), the valve offers flexibility for integration into diverse installations handling steam, gases, vapors, and liquids.

The Model 1216B combines compact design, compliance with international standards, and enhanced sealing performance, making it an ideal solution for engineers seeking reliable, code-compliant pressure protection with added operational safety.

The EF1216B is a compact spring-loaded safety and relief valve intended for steam, gases, vapours and liquids, with threaded or flanged connection options depending on configuration. It is particularly suitable for process equipment and packaged systems where a compact flanged PSV is preferred.
The EF1216 is primarily a threaded BSP/NPT safety valve. The EF1216B provides greater connection flexibility through threaded or flanged configurations and incorporates sealing features intended to improve tightness and containment.
The EF1216B can be particularly useful where: - The equipment specification requires flanged connections - PN or ASME flange ratings are specified - Improved seat tightness is required - A sealed lifting arrangement is preferred - The valve is integrated into OEM or packaged equipment
Yes. It can be considered for thermal-expansion duties where its capacity, set pressure and configuration are suitable for the calculated relieving requirement.
Yes. The EF1216B can be used for compatible: - Steam - Gases - Vapours - Liquids The selected pressure class, seat arrangement, temperature range and materials must match the actual service.
It can be considered for small steam equipment, packaged steam generators and auxiliary boiler systems when the required relieving capacity and applicable equipment requirements are within the valve's certified range.
It can be considered for sterilizers and packaged process equipment where a compact flanged or threaded safety valve is appropriate. Any hygienic, pharmaceutical or special equipment specification must be evaluated separately.
The EF1216B family includes configurations in: - PN16 - PN40 - Class 150 - Class 300 Threaded and flanged arrangements are available depending on configuration. The exact combination should be confirmed during quotation.
The O-ring disc can provide improved seat tightness compared with a conventional metal-to-metal configuration. This can be particularly useful for gases, compressed air and applications where leakage close to set pressure should be minimized.
The sealed lever allows the lifting function while helping reduce potential external leakage through the operating mechanism. This can be useful where improved containment is required.
ATEX configurations can be considered where applicable. The hazardous-area classification and required marking should be identified during the RFQ stage.
A PTFE-coated execution can be evaluated for compatible corrosive liquid duties. The actual chemical, concentration, temperature, pressure class and complete valve configuration must be reviewed before confirming suitability.
It can be evaluated for overpressure or thermal-expansion protection in compatible fuel systems, including Jet A-1 applications, where materials, sealing, set pressure and required capacity are suitable. No aviation-specific approval should be inferred automatically.
Accessories such as lifting or test devices can be considered according to the selected configuration and application requirements. The exact accessory scope should be confirmed during quotation.
The information normally required includes: - Fluid - Required capacity - Set pressure - Relieving pressure - Temperature - Backpressure - Threaded or flanged connection - PN or ASME pressure class - Sealing requirements - ATEX requirement - Applicable code - Inspection and documentation requirements
Delivery time depends on connection type, pressure class, sealing configuration, certification and project requirements. The applicable lead time is confirmed for each quotation.
Yes. Inspection, testing, technical documentation, material certification and project requirements can be incorporated into the agreed supply scope.
