Saunders® S360

 

Overview


The Saunders® S360 piston actuator permits remote operation of the valve, either as an alternative to manual operation or as an integral part of a control system. The S360 is a compact, lightweight, piston-type pneumatic actuator which has been developed to deliver superior performance for sterile BioPharm applications.


The Saunders® S360 housing is manufactured from polished 316 Stainless Steel producing a robust design, a clean OD profile and an attractive appearance. It can withstand typical industry wash down regimes.


The S360 is a piston-type actuator that provides reliable performance, high cycle life, lower air consumption and more compact design versus diaphragm type actuators.


The modular design offers two different spring- to-close versions; the S360 Lite with compact, lightweight design for typical applications and the S360 Power for maximum high pressure duty or for severe closure applications.


The S360 range also includes normally open, double acting, and options for limiting travel and direct switch mount variations. All models have a bright yellow visual indicator as standard.

Applications

 

 

The Saunders® S360 Actuator has been designed and engineered to deliver optimum performance over the full range of operating conditions found in bioprocess plants. The diaphragm in a weir type diaphragm valve has a large wetted surface that is exposed to pressure in the process line. This means that line pressure has a large impact on required actuator opening and closing forces.


The majority of applications produce pressure on one side of the weir only. This condition is typically called 100% pressure drop, or 100% ΔP. When this occurs, only half the wetted area of the diaphragm is exposed to line pressure.

100% Pressure Drop

line-pressure is on one side of weir only

This is the most common service condition.


The force on the diaphragm is greatest when there is pressure on both upstream and downstream sides of the weir. This condition is generally called 0% pressure drop, or 0% ΔΔP. When this occurs the total wetted area of the diaphragm is exposed to line pressure. This is not a common condition in BioPharm applications.

0% Pressure Drop

line-pressure is on both sides of weir

Maximum force is working against actuator.

Technical Details

 

Modular Design


The Saunders® S360 modular range delivers optimum dimensional envelope and closure performance. There are two different spring-to-close versions available; the S360 Lite and S360 Power actuator that delivers industry leading closure performance and allows complete flexibility to suit a wide range of pressure and flow conditions.

 

Saunders® S360 Lite


The S360 Lite range provides standard closure for normally closed applications in a very compact, lightweight package and is ideal for most applications. The S360 Lite fits into tight piping arrays – and its compact size can even help reduce block valve design and is available through sizes DN8 – DN100 (0.25” – 4.00”).

All pressures are gauge pressures. Line pressure values were determined with pressure on one side of the weir only. This condition is called 100% pressure drop, or 100% ΔP. Information on line pressure applied to both upstream and downstream sides of the weir is available on request.

 

Saunders® S360 Power


The Saunders® S360 Power range offers higher operating closure performance in a compact package for high operating pressure or atypical closing conditions with high pressure on both sides of the weir. The S360 Power spring-to-close actuator is available through sizes DN15 – DN50 (0.50” – 2.00”).
