Modular Valves

The Thermo Modular series of valves can be combined into a variety of configurations and are often used by the technical diver.  With a modular valve, the diver can use a modular cylinder valve as a stand alone valve with a single cylinder or combine into a dual manifold to dive with two cylinders.  Another option is to combine the modular cylinder valve with an H connector so that you can dive with a single cylinder and two regulators for maximum redundant security.

Modular Cylinder Valves

The first decision to make with the modular valve series is to determine which type of valve to put into your cylinder.  This valve can be used either by itself as a stand alone valve or combined into a dual manifold or combined with an H valve so that your cylinder will have two regulators attached.  The Modular Cylinder Valves come with either the Thermo PRO type outlet (shown to the left of this paragraph)  for pressures up to 230 Bar or the Thermo DIN type outlet (shown to the right of the next paragraph) for pressures up to 4350 psi.  Both types are available with a 3/4-14 NPSM inlet for most cylinders and valves with the Thermo DIN type outlet are also available with a 7/8-14 UNF inlet.

The second decision to make is whether you want a right hand or left hand valve.  If you ever wish to connect two modular valves together into a dual manifold, you must have both a right hand and a left hand valve.  But which valve is a left hand and which is a right hand?  The easiest way to remember this is to picture the valve installed in a cylinder mounted onto a BC and on your back - all ready to dive.  In this configuration, if the handwheel points to the right and you would use your right hand to operate it, then it must be a right hand valve.  In a like manner, if the handwheel points to the left and you would use your left hand to operate it, then it must be a left hand valve.  (Please note a picture of a left hand valve on the left side of the above paragraph and a picture of a right hand valve on the right hand side of this paragraph.)

Center Bars for Dual Manifold Valves

If you wish to dive with two cylinders manifolded together, you will also need a center bar to connect the two valves.  There are two center bars available depending on which size cylinders you wish to manifold.  The 8002 CTR W VLV center bar comes with a center isolator valve and when attached to two modular valves will separate the cylinders by 215 mm from center to center.  This center bar is used for most cylinders.  Also available is the 8004 CTR BAR without a center isolator valve and when attached to two modular valves will separate the cylinders by 185 mm from center to center.  This is usually used to manifold two 40 cubic foot cylinders together.
