Customization for Severe Service
For special temperatures, corrosive media and emergency shutdown requirements, we define valve, actuator and control accessory packages based on actual operating conditions.
Customized Solutions for Severe Service
For special temperatures, corrosive media and emergency shutdown requirements, we define valve, actuator and control accessory packages based on actual operating conditions.
Typical Applications
Special Temperature Conditions
For low- or high-temperature media, verify materials, seals and actuator ambient conditions across the complete temperature range.
Provide temperatures and pressures during normal operation, startup and abnormal conditions, together with insulation and installation-clearance requirements. Applicability must be confirmed for the specific product configuration.Corrosive and Complex Media
Discuss wetted materials, seal construction and maintenance for acids, alkalis, particle-laden or crystallizing media.
Provide the medium name, concentration, temperature, particle characteristics and cleaning procedure so that body, trim and seal materials can be confirmed for compatibility.Emergency Shutdown and Integrated Interlocks
Confirm normally open or normally closed status, air-loss and power-loss actions, and valve position feedback requirements according to the site control logic.
Provide shutdown time, operating frequency, air supply pressure, control signals, and explosion protection or functional safety requirements. Confirm the scope of certification, testing and acceptance item by item in the technical agreement.Recommended Products
