Saunders pneumatic actuators permit remote operation of the valve, either as an alternative to manual operation or as an integral part of a control system.
The EC is a compact, lightweight piston-type pneumatic actuator developed specifically for BioPharm applications. The housing is manufactured from PES (polyethersulphone), a high performance thermoplastic. PES is known for its outstanding strength, chemical resistance and thermal properties. The EC features compact size and a smooth exterior profile that includes shrouded fastener design for 2-way bodies and slotted base for use on block type bodies.
EC actuators are available in sizes DN8 – DN50 (0.25” – 2.00”). All three operating modes: double acting, spring-to-close and spring-to-open use the same housing and share the same reduced overall size.
Saunders ECX type actuators are designed to offer an extension to the EC size range while maintaining a compact envelope size. The ECX is available in sizes DN65–DN150 (2.50” – 6.00”). The housing is manufactured in coated silicon aluminium for optimum chemical resistance and long life. With an extensive range of spring packs available,
Saunders offers an actuator to suit a wide range of pressure and flow variations. Available in spring close, spring open, and double acting modes of operation to suit process needs. A wide range of options including switches, positioners, limit stop and visual open/close indication are also available.
