What materials are used in the valve construction?

The housing is MADE from die-cast aluminium and elastomeric Seals are NBR to provide a balance of strength and fluid sealing.

How does the valve perform under low-pressure conditions?

It operates down to -0.95 bar, enabling use in applications that require slight vacuum or negative gauge pressures.

What service-life data is available for long-term planning?

A characteristic service-life B10 Value is specified as 5 million cycles based on standard pneumatic reliability assessment.

Are there specified test Pulse tolerances for signal switching?

Maximum positive test Pulse with a 0 signal is 2200μs and maximum negative test Pulse with a 1 signal is 3700μs.
