Design and Operation

The pneumatic actuator provides remote quarter-turn opening and closing, while the full-bore straight-through flow path is intended to reduce restriction in the open position. Actuator type, output torque, air pressure, cycle time, accessories and fail position are project selections and are not defined by the valve model alone.

Media and Service Limits

The stock record lists water, steam and oil and a maximum operating temperature of 300 C. Confirm the F304L pressure-retaining material, cemented-carbide sealing surface, stem packing and body-joint materials for the actual fluid, temperature, pressure and operating frequency.

Standards and Project Verification

The source identifies the Chinese national standard system but does not state every governing code. Confirm the design, flange, face-to-face and testing standards, along with actuator sizing, leakage criteria, material certificates and control-interface requirements before ordering.
