Automatic valves

Blocking valves Series VBO – VBU

Unidirectional valves (VBU) and bidirectional valves (VBO) Ports G1/8, G1/4, G3/8 and G1/2 Tube diameter: 6, 8, 10, 12 mm
These unidirectional and bidirectional blocking valves have been realised in order to enable mounting directly on cylinders. They can be used as high flow valves for blows, cleaning of pieces, filling of volumes. For these applications it is suggested to connect the supply to port 2 (having the mail thread). These valves can be mounted directly also on distribution and fluid control blocks.

Check valve – Union straight Mod. CLVNR – Inch

In-Line Non-return Valves Used where air flow passes only in one direction. Used where the air pressure is required to remain constant on the exhaust side.

Quick exhaust valves Series VSO, VSC

Series VSO ports: M5, G1/8, cartridge Ø4 Series VSC ports: G1/8, G1/4, G1/2
Series VSC and VSO quick exhaust valves are commonly used to increase the speed of cylinders or for rapid depressurisation of tanks containing compressed air. Mod. VSO 425-M5, VSO 426-04: they are particularly suitable to be mounted on solenoid valves and valves incorporating a ø 4 cartridge. Mod. VSO 4-1/8: it is particularly suitable for direct mounting on the actuator connection. The air coming in from the jointed part (1) is used by the threaded side (2), whilst the exhaust (3) passes through the holes sideways to the valve body. Mod. VSC: they are particularly suitable to be mounted directly on the cylinder mouth through the use of a nipple. It is recommended to mount a silencer on the outlet.

Unidirectional valves in 316L stainless steel Series XVNR

Series XVNR unidirectional valves are suitable to be used in low pressure applications, in environments with aggressive fluids or gases.

Unidirectional valves Series VNR

Ports of Thread version: M5, G1/8, G1/4, G3/8, G1/2, G3/4, G1 Dimensions of Tube/Tube version: Ø4, Ø6, Ø8, Ø10, Ø12
Series VNR unidirectional valves are available in the Thread or Integrated Fitting version. Thanks to their construction they operate at low pressures.
