The Asco 8263G232LT Solenoid Valve is a direct-acting, normally closed valve configured for cryogenic fluid control. Built for service with liquefied nitrogen, argon, and oxygen, it handles temperatures as low as -320°F and pressures up to 130 psi. This model is suited for small-bore pipelines requiring accurate shutoff at zero inlet pressure.
