Ross Controls has announced the release of its Dale Series leak-test (LT) pneumatic valves and manifolds.

These continuous-duty rated valves provide high-flow capability in a compact, lightweight package and offer non-lube service for ease of use.

The Series LT valves are part of a recent trend in leak-test systems that utilise a manifold block design.

This configuration allows customers to leak test without added piping.

Its integrated flow and pressure sensor ports also decrease test volume and the need for extra fittings.

The bubble-tight design provides excellent sealing capabilities and provides a long service life in dirty environments, according to the company.

The valve’s independent internal poppet design also allows it to adapt to various system design requirements.

As a result, the Series LT valves are suitable for a broad array of applications including:counterbalance and cushions, pick and place, glass, poppet cartridges, directional control, pressure isolation or decay test, bypass fill or isolation valves, flow test, differential or two-channel pressure decay test, integration with cylinders for speed and energy savings, and low-pressure fluids for steel processing.

The Series LT has a leak-tight design, so there is no leak path from pilot pressure to the test chamber, meaning energy consumption is reduced.

The product also offers minimal energy consumption and reduced heating effects due to its low 1.2W solenoids.

In one application, the Series LT valves replaced an 18W product, instantly solving a customer’s excessive heating effect problem.

The Series LT valves are available in 2/2, 3/3 and 3/4 with 1/4in ports, or 4/4 and 5/4 with 1/2in size ports, all with normally closed configurations.

The valve’s internal 1/2in orifice has a flow range from 2.2 to 5.0 CV.

For flexible design application, the valves are port pressure independent and can be field configured for flow, pressure decay or differential pressure testing.
