Temperature Regulators For Heating & Cooling Applications

W91H/C • Non-Indicating
W94H/C • Indicating - With Dial Thermometer

 

Used For Heating with Steam or for Cooling with Water along with Mixing/Diverting options as well as Domestic Hot Water Valves upon request.

Normally Open Valves are used for HEATING, so the valve stem closes (in-to-close)  Fail position is (Normally Open)

Single-Seated Balanced Valves are used for HEATING Applications (normally steam) where tighter shut-off is required. Leakage rate is approximately 0.01% of the maximum capacity (Class IV shut-off).

 

Normally Closed Valves are used for COOLING, so the valve stem opens (in-to-open) Fail position is (Normally Closed)

Double-Seated Balanced Valves are used for COOLING Applications where larger flow rates of water are required, and a small leakage rate through the valve is normally acceptable. Leakage rate can be up to 0.5% of the maximum valve capacity (Class II shut-off).
