FAQs

What is the valve function and operating structure of VUVS-LT20-M52-MD-G18-F7?

It is a 5/2 monostable solenoid valve with electrical actuation and a poppet seat design. Reset is provided by a mechanical spring, using a soft sealing principle.

What are the key switching-time and test-pulse specifications?

Switching time off is 19 ms and switching time on is 15 ms. Maximum positive test pulse with logic 0 is 1,900 µs, and maximum negative test pulse with logic 1 is 2,700 µs.

How should the pneumatic and pilot connections be configured?

Pneumatic ports 1–5 use G1/8 connections, while the pilot exhaust port 84 uses M5. The valve supports internal pilot air supply and non-reversible flow direction.
