ASTA P533 and P543 are single-seat two-way high-temperature control valves controlled by an electric/pneumatic actuator. They are designed for precise remote control or shutoff of the working medium flow. The valve is used in high-temperature process systems.

Design features

• Cooling fins on the housing cover
• Stelliting of the internal parts of the valve (up to 425°C)
• Metal-to-metal sealing on the shutter
• Repairable design
• Various designs of valve flange sealing surfaces are optionally available (versions C, L, D, M, etc.)
• Upon customer request, it is possible to install electropneumatic positioners with standard 4…20 mA control, as well as with additional options (feedback, HART protocol, PROFIBUS, explosion protection, etc.)
