Product Description

The SMC Chemical Liquid Valve (MPN LVQ31-Z11R) is a 3/8 in high-purity pneumatically-actuated diaphragm valve with an Air to Spring actuator operation and a Fail Open fail-safe position. This PFA valve features a 1/8 in BSPT connection and operates within a temperature range of 0°C to 60°C.

Frequently Asked Questions

What is the SMC LVQ31-Z11R chemical liquid valve used for?

The SMC LVQ31-Z11R is a high-purity pneumatically-actuated diaphragm valve designed for controlling chemical liquids in semiconductor, pharmaceutical, and industrial processing applications. Its PFA body and Fail Open fail-safe position ensure safe shutoff on loss of air pressure, protecting sensitive processes from contamination.

What are the specifications of the SMC LVQ31-Z11R valve?

The SMC LVQ31-Z11R is a 3/8 in high-purity diaphragm valve with Air to Spring actuator operation and a Fail Open fail-safe position. It has a PFA body, a 1/8 in BSPT connection, and operates from 0°C to 60°C. The manufacturer part number is LVQ31-Z11R.

Where to buy the SMC LVQ31-Z11R valve worldwide?

You can source the SMC LVQ31-Z11R valve through 3G Electric, a global industrial equipment distributor established in 1990. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this SMC high-purity diaphragm valve.

How to install the SMC LVQ31-Z11R valve?

Install the SMC LVQ31-Z11R valve by ensuring the piping is clean and the 1/8 in BSPT connection is properly sealed. Mount the valve in a position that allows the diaphragm to operate freely. Apply air pressure to the actuator for normal operation; on loss of air, the valve fails open. Follow SMC's generic guidelines for pneumatically-actuated diaphragm valves.
