FAQs

The EF600 protects process vessels, storage tanks, compatible process equipment and vent systems against excessive positive pressure, excessive vacuum or both. Its configuration must match the vessel design conditions, required settings and relieving capacity.
It can. The EF600 platform is available as a pressure-only valve, a vacuum-only valve or a combined pressure-vacuum breather valve. The combined configuration provides separate positive-pressure and vacuum protection in one assembly.
Yes. The positive-pressure configuration operates as a compact spring-loaded safety or pressure relief valve. Final selection and applicable conformity requirements depend on the protected equipment, fluid, set pressure and required capacity.
The published positive-pressure calibration range is +0.01 to +5 bar(g), and the published vacuum range is -0.01 to -0.9 bar(g). Actual availability depends on valve size, materials, seat, connection and service conditions.

ABOUT EF600

The EF600 pressure, vacuum and breather safety valve is a configurable relief platform for protecting vessels, process equipment and vent systems against positive pressure, vacuum or both conditions. The same product family can be specified as a pressure relief valve, a vacuum relief valve or a combined pressure-vacuum breather valve according to the required function.

Its compact multi-size design covers nominal sizes from DN20 to DN150. Published calibration ranges extend from +0.01 to +5 bar(g) for positive-pressure relief and from -0.01 to -0.9 bar(g) for vacuum relief. The series has a published maximum allowable pressure of 10 bar(g) and a temperature envelope from -40°C to +200°C, with final limits depending on material, seat, size, connection and service conditions.

Stainless steel 316L is the standard construction, with Hastelloy available for more demanding media. Metal seating is standard, while Stellited metal, EPDM, FKM, FFKM and virgin PTFE seat options allow the sealing arrangement to be matched to chemical compatibility, tightness and temperature requirements. Connection choices include male or female BSP/GAS and NPT threads, EN 1092-1 or EN 1759-1 flanges, ISO and DIN hygienic clamps, SMS 1145 and engineered connections on request.

The EF600 is suited to chemical, petrochemical, gas, storage-tank, food-and-beverage, cosmetic and pharmaceutical duties where compact installation and broad configuration flexibility are required. An inductive position sensor and atmospheric outlet arrangements can be specified. PED/CE, ATEX and project documentation are evaluated for the selected configuration and application rather than assumed universally.

Frequently Asked Questions

The EF600 protects process vessels, storage tanks, compatible process equipment and vent systems against excessive positive pressure, excessive vacuum or both. Its configuration must match the vessel design conditions, required settings and relieving capacity.
It can. The EF600 platform is available as a pressure-only valve, a vacuum-only valve or a combined pressure-vacuum breather valve. The combined configuration provides separate positive-pressure and vacuum protection in one assembly.
Yes. The positive-pressure configuration operates as a compact spring-loaded safety or pressure relief valve. Final selection and applicable conformity requirements depend on the protected equipment, fluid, set pressure and required capacity.
The published positive-pressure calibration range is +0.01 to +5 bar(g), and the published vacuum range is -0.01 to -0.9 bar(g). Actual availability depends on valve size, materials, seat, connection and service conditions.
The EF600 is available from DN20 to DN150. Final sizing must be based on the required pressure-relief or vacuum-relief capacity and allowable overpressure or overvacuum, not only on the connecting pipe size.
Stainless steel 316L is the standard body material and Hastelloy can be evaluated for demanding corrosive media. Seat options include metal, Stellited metal, EPDM, FKM, FFKM and virgin PTFE, subject to fluid compatibility and temperature.
Available connection concepts include male or female BSP/GAS and NPT threads, EN 1092-1 and EN 1759-1 flanges, ISO 2852, ISO 1127 and DIN 11866-C clamps, SMS 1145, atmospheric outlets and engineered connections on request.
Yes, where the selected EF600 configuration, connections, surface finish, materials, seats and process requirements are suitable. The exact hygienic, cleaning and documentation requirements should be defined during the RFQ stage; suitability or certification should not be inferred from a clamp connection alone.
Vacuum can develop during operating conditions such as liquid withdrawal, cooling or condensation, depending on the process. Where these scenarios are credible, the required vacuum-relief capacity should be considered when selecting the EF600 configuration.
Where the selected configuration includes the optional inductive position sensor, valve movement or opening feedback can be integrated into the project control system. The required electrical classification and interface should be defined during the RFQ stage.
Available project documentation may include a technical sheet and sectional drawing, PED/CE declaration, ATEX documentation when applicable, EN 10204 3.1 material certification, conformity and test records, gas capacity calculations and installation or maintenance instructions. The exact package depends on the selected configuration and contractual scope.
Yes. It can be considered for cosmetic-process vessels where pressure or vacuum protection is required and the selected valve configuration is compatible with the process conditions.
Seat selection depends on chemical compatibility, temperature and the required sealing performance. The complete process conditions should therefore be reviewed before selecting the appropriate EF600 seat configuration.
Yes, where an available EF600 material and seat configuration is compatible with the actual process fluid and operating conditions. Final selection should be based on fluid composition, temperature, corrosion requirements and the project specification.
Typical information includes the process fluid and composition, pressure and vacuum settings, separate pressure-relief and vacuum-relief capacities, allowable overpressure and overvacuum, operating temperature, vessel or tank design conditions, connection, body and seat materials, installation arrangement and documentation requirements. These data allow the pressure-only, vacuum-only or combined configuration to be reviewed correctly.
Yes. The EF600 can be considered for EPC and project-managed applications where the required relief function, settings, capacities, materials, connections, instrumentation and documentation requirements are defined during the RFQ stage. Final configuration should be confirmed against the actual vessel and process data.
