Thermo vavle by XS Scuba. This is a left hand valve (non standard side), modular (can be built into a manifold) with vindicator valve. Valve was previously 02 cleaned but not recently. Burst disc assembly is currently appropriate for HP 3442psi cylinders with a 5250psi burst disc. Excellent valve, especially if you're looking for a mate for a sidemount set. These retail for around $125.
