Never heard of them.... Google doesn't provide good results either...
maybe
Welcome to ELLock.com, but I can't be sure as they block that site at work and I can't access it. will try to check tonight.
EDIT: one thing about Thermo Valves, you can order rebuild kits for those valves from about any shop out there.... As for EZ-Lock, hard to order a rebuilt kit if you've never heard of them before....
I replied asking for a link to the manufacturer site. The link you provided does show an EZ Tex valve but I can't get the description page to load here at work.
Probably end up just getting a Worthington online with a Thermo or XS.
EDIT:
EZ Tex-2 Ez Tex-3 Coming Soon...

FULL MANUFACTURER'S WARRANTY
Ez Tex standalone and modular SCUBA tank valve. All SCUBA valves are polished triple-bright chrome-plated brass for maximum protection and long-lasting beauty in salt water environments. During the manufacturing process, every valve is tested under high pressure to check for leaks and ease-of-operation. All valves and parts include a one-year limited warranty against defects in materials and workmanship.
The outlet on the K valve is designed with twin dimples in the bottom section of the o-ring keeper. This helps to avoid o-ring blowout when disconnecting your first stage regulator. The K type outlet is used on valves with service pressures up to 230 Bar.
All scuba valves are triple bright chrome plated for maximum protection and long lasting beauty in salt water environments. The new Easy Grip handwheel is made from soft rubber formed around a durable stainless steel insert. The stainless steel insert insures positive long lasting life. The large soft rubber ribs make it easy to open or close the valve even while wearing dive gloves.
All scuba valves come with a one piece safety plug assembly which eliminates the possibility of mismatched components and can be used on all prior versions of scuba valves. This greatly reduces the likelihood of accidental "double disking" of the safety assembly and protects the integrity of your diving cylinder. The safety device is shielded by the valve body to avoid damage during transportation or while diving.
All scuba valves come with a high pressure plug & seat assembly manufactured from a high tensile brass alloy and the threaded area is coated with Teflon. Both the high tensile brass and the Teflon coating insure a lube less, smooth operation and prolongs the life of your valve! During the manufacturing process every valve is pressure tested under high pressure to test for leaks and ease of operation at operating pressures.
All valves are manufactured to help lifting easier by using a longer handle.
The K-valve is by far the most common valve on SCUBA cylinders in the U.S. and nearby areas, such as the Caribbean. The regulator first stage attaches to this valve using a yoke A-clamp fitting, and there is a sealing O-ring that is held in the face of the valve outlet where it mates with the regulator. Although this system has been in use a long time, it is considered by many to be somewhat unreliable.
The Deutsches Institut Für Normung (DIN) is a German standards setting organization similar to our American National Standards Institute (ANSI) and Compressed Gas Association (CGA). DIN 477 is a specification that recommends cylinder valve outlet and connector designs for specific types of gases and pressures based upon safety considerations. These various designs have deliberate incompatibilities to preclude the possibility of errors when handling different types of compressed gases at differing working pressures. The two valve outlets and connectors of interest for divers are the DIN 477 No. 13 and the DIN 477 No. 56 (formerly No. 50), both designated for use with compressed air. The DIN 477 valve and regulator fittings are most widely used outside the U.S. The regulator first stage DIN connector is a male screw type, and instead of clamping on to the outside of the valve as does the yoke, it screws directly into the female DIN outlet of the valve. The sealing O-ring is held in the end of the regulator connector rather than in the face of the outlet. The DIN 477 system, with it's captured o-ring design, has proven to be very reliable for use with SCUBA.
Outlet/Connector #13 is from DIN 477 part 1 - for cylinders with test pressure ratings up to 300 bar and is commonly referred to in the SCUBA industry by the slang term "200 bar", probably because most cylinders with 300 bar test pressures have working pressures in the 200 bar range. Outlet/Connector #56 is from DIN 477 part 5 - for cylinders with test pressure ratings up to 450 bar and is commonly referred to in the SCUBA industry by the slang term "300 bar". The two designs are nearly identical, but the #56 valve outlet is deliberately deeper so the shorter #13 connector will not be long enough to seat properly. This is a safety feature to prevent connecting a low pressure device to a high pressure supply. It's important to understand that the "200 bar" or "300 bar" descriptions are just slang terms that have nothing to do with the pressure ratings of the outlets and connectors themselves!
