Heatguard
®
145 Series–Lead Free
DESCRIPTION
The Heatguard
®
145 is a compact Thermostatic Mixing Valve that mixes hot water with cold to
deliver tempered water at a constant temperature.
The Heatguard
®
145 is specifically intended for use in conjunction with individual faucets and
electronic sensor faucets.
The Heatguard
®
145 is a compact, high specification product incorporating the latest in
Thermostatic Technology. It features a robust design based on the expertise gained from years
of experience in the design and manufacture of safety valves. Every valve is tested for
performance on an automated testing station during the assembly process. The valve is third-
party listed for individual point-of-use applications.
The Heatguard
®
145 features a rapid response thermostatic element for superior control. The
thermostatic element senses the outlet water temperature and reacts to maintain a constant
delivery temperature even under changing flows or variations in supply temperatures or
pressures. It provides stable operation at flow rates as low as 0.34 gpm (1.3 l/min). The valve
also reduces the outlet flow to a trickle in the event of a cold water supply failure.
The Heatguard
®
145 features a snap-on cover over a spindle mechanism that requires a
special tool to adjust the temperature. The special tool is provided with each valve.
The Heatguard
®
145 has inlet connections to suit a 3/8" flexible hose connector or a
compression connection to 3/8" OD tube. Also available with cold water bypass and elbow
insert fittings. Supplied standard with integral check valves on both inlets to prevent cross-flow
and strainer screens to prevent contaminate build up.
FEATURES AND BENEFITS
Compact design:
Easily fits under or behind a single basin.
Mounting clamp included:
Securely mounts to the wall.
Strainer screens provided for the hot and cold inlet:
Prevents foreign contaminate from creating blockages in the valve.
Accurate temperature control with flows as low as 0.34 gpm (1.3 l/min):
Increased user comfort and convenience, (especially with sensor faucets).
Robust, low complexity construction:
Superior reliability, improved user safety.
Total flow shut-off if cold supply fails:
Greater end user safety.
Listed by IAPMO, CSA, and ASSE:
Inspector friendly, peace of mind!
Use with SharkBite®:
Easily connect to the riser with SharkBite® 1/4” fittings and stops.
SPECIFICATION
A Temperature Actuated Mixing Valve shall be installed at single point-of-use fixture to deliver
hot water at a controlled temperature. The valve shall be certified to ASSE 1070 and CSA B
125.3 standards and third party listed. The temperature actuated mixing valve shall control the
delivered water temperature via a regulating piston made from engineered polymer. The valve
should have check valves at both inlets to prevent cross flow from hot to cold. The adjusting
mechanism shall be protected by a snap-on cover. The valve shall be a Cash Acme
