Temperature and Pressure Control Valves | Boiler Supplies Steam Temperature Control Valves Watson McDaniel W91/W94 Series Temperature Regulators
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).
Model W91H Non-Indicating No Dial Direct Acting Heating Regulator is ideal for regulating the temperature of tanks, process steams and various types of industrial equipment.
Model W94H Indicating With Dial Direct Acting Heating Regulator is ideal for regulating the temperature of tanks, process steams and various types of industrial equipment.
