Medical valve Series 8

solenoid

2/2-way - Normally Closed (NC) 3/2-way - Normally Closed (NC) Series 8 pneumatic operated valves are particularly suitable for applications requiring high flow combined wtih compact design. The valve is pneumatic operated by electro-pilots which are dimensioned according to the size. The cartridge design, which is ideal for manifold assembly, allows to reduce both dimensions and the number of pneumatic connections. The standard function of the valve is 2/2-way NC. It can however fulfill the 3/2-way NC function if inserted in a proper seat (see the following pages). 2/2-way - Normally Closed (NC) 3/2-way - Normally Closed (NC) The Series 8 enlarges the range of versions available with the cartridge valve directly integrated in an anodized aluminium body comprising also the pilot solenoid valve. The new bodies enable to have pneumatically operated versions with external piloting or electropneumatically operated versions with both external and internal piloting.
