Mini vacuum pump
Mini chip vacuum pump works with low and fluctuating compressed-air pressures. At inlet pressure of 55 psi, the pneumatically driven pump provides down to 24.1 inches Hg of vacuum pressure. The small pumps are available with numerous mounting arrangements for end-of-arm tooling and other applications where space is limited. The pumps are also said to be efficient and maintenance-free.

Directional valve
These directional seated valves use spring-loaded balls as valve elements for eliminating leakage. The valves are mounted individually or in combination with connection blocks to manifolds, and are mechanically and manually activated with a solenoid or pressure from pneumatic or hydraulic systems. All activation methods use an angled lever that pushes the valve element into the desired switching position. The 2/2 and 3/2 valves are used in applications up to 10,000 psi.
