Product Description

The SMC Chemical Liquid Valve is a high-purity pneumatically-actuated diaphragm valve with a 3/8 in connection. It features Air to Spring actuator operation and a Fail Closed fail-safe position, with a PFA body and 1/8 in BSPT port. The valve operates within a temperature range of 0°C to 60°C, as specified by manufacturer part number LVQ30-Z11R-9.

Frequently Asked Questions

What is the SMC LVQ30-Z11R-9 chemical liquid valve used for?

The SMC LVQ30-Z11R-9 is a high-purity pneumatically-actuated diaphragm valve designed for controlling chemical liquids in semiconductor, pharmaceutical, and industrial processing. Its PFA body and Fail Closed fail-safe position ensure safe shutoff on loss of air pressure, protecting sensitive processes from contamination or leakage.

What are the specifications of the SMC LVQ30-Z11R-9 valve?

The SMC LVQ30-Z11R-9 features a 3/8 in connection, Air to Spring actuator operation, Fail Closed fail-safe position, PFA body, and 1/8 in BSPT port. It operates from 0°C to 60°C. The manufacturer part number is LVQ30-Z11R-9, and it is a pneumatically-actuated diaphragm valve from SMC.

Where to buy the SMC LVQ30-Z11R-9 valve worldwide?

You can source the SMC LVQ30-Z11R-9 valve worldwide through 3G Electric, a global industrial equipment distributor since 1990. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we supply genuine SMC components for chemical liquid applications.

How to install the SMC LVQ30-Z11R-9 chemical liquid valve?

Install the SMC LVQ30-Z11R-9 by connecting the 1/8 in BSPT port to your piping system, ensuring PFA compatibility with your chemical media. Apply air pressure to the Air to Spring actuator for normal operation; the valve fails closed on pressure loss. Follow SMC's generic diaphragm valve best practices for torque and sealing.
