If you need the temperature﹑pressure﹑flow control coefficient parameters please call for consultation.
The Spirax SarcoKE series control valves andPN5000 and PN6000 pneumatic actuators are used for the precise control of steam﹑water﹑oil and most industrial fluids.
The standardized design and diverse options of the KE series control valves allow one valve to meet various industrial requirements.
After being installed withPN5000 (normally open) or PN6000 (normally closed) pneumatic actuators, the KE valve can be used in various devices for flow, pressure, or temperature control.

Spirax Sarco KE73 Pneumatic Control Valve is a corrosion-resistant straight-through single-seat control valve, with the inner wall of the valve body and valve components in contact with the fluid made using high-pressure injection molding technology, lined with corrosion-resistant and aging-resistant polytetrafluoroethylene (F46), and uses a polytetrafluoroethylene corrugated pipe seal. This control valve is widely used for controlling strong corrosive media such as acids and alkalis, as well as toxic and volatile gases and liquids.
The corrosion-resistant control valve lined with fluorine rubber is widely used for controlling strong corrosive media such as acids and alkalis, as well as toxic and volatile gases and liquids.
1. Corrosion-resistant. It can resist the corrosion of almost all media (including concentrated nitric acid and aqua regia).
2. Good sealing performance. It adopts a double seal of a corrugated pipe and packing to ensure no leakage.
3. Low leakage. Due to the soft sealing of the valve core and valve seat, it ensures no leakage.
4. Paired with HA actuators, it has a large output force and compact structure. The product meets GB/T4213-92.
