Product Description

The SMC Chemical Liquid Valve (SKU 3G-OTH-449930) is a high-purity pneumatically-actuated diaphragm valve with a 1/4 in connection. It features Air to Spring actuator operation and a Fail Closed fail-safe position, with a manufacturer part number of LVQ20-Z07R-9.

Frequently Asked Questions

What is the SMC LVQ20-Z07R-9 chemical liquid valve used for?

The SMC LVQ20-Z07R-9 is a high-purity pneumatically-actuated diaphragm valve designed for precise control of chemical liquids in semiconductor, pharmaceutical, and industrial processing. Its PFA body and fail-closed air-to-spring actuator ensure safe shutoff on loss of air pressure.

What are the specifications of the SMC LVQ20-Z07R-9 valve?

The SMC LVQ20-Z07R-9 has a 1/4 in connection, 1/8 in BSPT port, PFA body, air-to-spring actuator, fail-closed position, and operates from 0°C to 60°C. It is a high-purity pneumatically-actuated diaphragm valve for chemical liquid service.

Where to buy the SMC LVQ20-Z07R-9 valve worldwide?

3G Electric supplies the SMC LVQ20-Z07R-9 valve worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this high-purity pneumatically-actuated diaphragm valve.

How to install the SMC LVQ20-Z07R-9 fail-closed valve?

Install the SMC LVQ20-Z07R-9 in a clean, dry location with proper support for piping. Ensure the 1/8 in BSPT ports are aligned and tightened to manufacturer torque specs. Connect the air supply to the actuator; the valve defaults to closed on air loss. Test for leaks before service.
