3 Overview Thermostatic Control Valve - Model AMOT Model thermostatic valves are available in a wide selection of sizes and settings to fill a multitude of fluid temperature control requirements. These valves may be mounted in any position and use the proven expanding wax principle to actuate the -way temperature element assemblies. The model valves may be used for diverting or mixing service. They make very economical temperature limiting valves for engine and lubricating oil cooling, and to prevent scalding in hot water supply systems; such as in emergency water systems for labs. Radiant heating systems can use these valves in limiting water temperature to prevent surface cracking and over-heating of plastic piping. Other applications include electronic and battery cooling circuits, pump temperature relief valves etc. Housing materials Cast iron Steel Ductile iron ronze Stainless steel Seal materials una N/Nitrile Viton Neoprene Element materials A combination of bronze, brass and stainless steel (standard) A combination of nickel plated and stainless steel Leakholes In some applications, it is necessary to have leak holes drilled in the element to ensure a small flow between ports A and C. Leak holes are available in sizes ranging from. mm -.7 mm ( - ). Temperature settings A wide selection of element materials, seals, and temperatures are available. Follow the equipment manufacturers guidelines for heating/cooling systems. Temperature settings are available from C - C (55 F - 40 F). Refer to the temperature and element characteristics table on page 7 for specific temperature settings. In general, the temperature quoted is the nominal operating temperature in diverting mode on water systems. Manual override (M & R) Model M For M type valves, in automatic mode the valve will control the temperature automatically, but actuating the manual override mechanism(s) on top of the valve will move the element(s) to the fully extended (hot) position, regardless of temperature. Each element assembly has its own manual override. Please refer to the Leakhole size (G) section of the valve selection table on page 8 to determine the hole size required for specific applications. For long life, AMOT valves should not be operated continuously at temperatures in excess of 4 C (5 F) of their maximum continuous rating. If this condition is anticipated then consult AMOT for suitable alternatives. For mixing and oil circuits the temperature may be one to two degrees higher due to flow, viscosity and other system parameters. Elements and seals are available in a variety of materials. These materials are suitable for most applications. Please contact AMOT for material compatibility information. Model R R type valves are fitted with a manual override which allows a progressive opening of port A to C. Manual override is often a requirement for marine applications. Each element assembly has its own manual override. Manual override should only be used in case of an emergency or element failure. Datasheet Thermostatic_Control_Valve_08 rev 4 Page

4 Applications Diverting Applications When valves are used for diverting services, the inlet is Port A (temperature sensing port), with Port C being connected to the cooler, and Port connected to the cooler bypass line. Heat Load Pump A C AMOT Thermostat Pressure drop (Metric units) Thermostatic Control Valve - Model Heat Removal Cooler Valve Characteristics Pressure drop (bar) Mixing Applications When valves are used for mixing service, Port C is the cold fluid inlet port from the cooler, Port is the hot by-pass fluid inlet, and Port A the common outlet. Port A is the temperature sensing port and will mix the hot and cold fluids in the correct proportion so as to produce the desired outlet temperature leaving Port A. Heat Load AMOT thermostatic valves are designed to produce minimal pressure drop. The normal recommendation in sizing the valves is to select a pressure drop between bar ( - 7 psi).

It is defined as the flow rate in cubic meters per hour (m /hr) of water at a temperature of º Celsius with a pressure drop across the valve of bar. The basic formula to find a valve s Kv is shown below: Kv = Q SG DP Q = Kv DP SG DP = Q SG Kv Q = Flow in m /hr DP = Pressure drop (bar) SG = Specific gravity of fluid (Water =.0) Kv = Valve flow coefficient (Metric units) Cv is the imperial coefficient. It is defined as the flow rate in US Gallons per minute (gpm) of water at a temperature of 0º Fahrenheit with a pressure drop across the valve of psi. The basic formula to find a valve s Cv is shown below: Cv = Q SG DP Q = Cv DP SG Q DP = Cv SG Q = Flow in US Gallons/Min DP = Pressure drop (psi) SG = Specific gravity of fluid (Water =.0) Cv = Valve flow coefficient (English units) Datasheet Thermostatic_Control_Valve_08 rev 4 Page 5

6 Thermostatic Control Valve - Model Valve Characteristics Continued Viscosity correction For the selection of valves for use with more viscous fluids than water, the following must be calculated in addition to using the previously mentioned formulae: Viscosity Find the viscosity of the fluid to be used in the valve. This will generally be in centistokes (cst). ISO grade oil is easy to calculate as the grade no. is the viscosity. I.e. ISO VG 4 = 4 centistokes at 4 C (0 F) Viscosity correction curve (Fv).0 Viscosity correction Once the viscosity value has been found, the flow coefficient correction factor can be established using the viscosity correction graph below. The correction value (Fv) that is produced by the graph should then be multiplied by the original flow coefficient. This gives the corrected flow coefficient, which can then be used in the standard formula. e.g.: 00 cst = correction factor of x flow co. = corrected flow co. (Kv or Cv) 0.

12 Thermostatic Control Valve - Model Maintenance and Service Parts Over time, exposure to foreign chemicals and particulate matter as well as prolonged operation at extreme conditions may reduce the effectiveness of the valve. At such time, AMOT Thermostatic Valves can be restored to original performance by installing an AMOT thermostatic valve service kit or a seal kit and new temperature element(s). Service kits are ONLY available for purchase from the Americas and Canada locations. If ordering from the Europe or Asia-PAC locations please purchase a seal kit and element to properly service your valve. Service kits include all new thermostatic element(s), seals and gasket required for normal maintenance. Seal kits include new seals and gasket(s). Whenever element(s) are replaced, the seals and gasket(s) should also be replaced. Ordering from Americas and Canada Service kits Service kits are ONLY available for purchase from the Americas and Canada locations. Service kits are available with element(s), seals and gasket required to service the valve. Order service kits using the AMOT valve part number and nominal temperature setting. Refer to the AMOT valve part number that is printed on the valve nameplate and the AMOT valve part number structure on page 8. The nominal temperature setting is also stamped onto the element flange. AMOT recommends fully servicing thermostatic control valves with each regularly scheduled major overhaul of the turbine, engine, compressor or other associated equipment. AMOT recommends a service interval of not more than 4 months to ensure optimum valve performance. AMOT designs and tests all its products to ensure that high quality standards are met. For good product life, carefully follow AMOT s installation and maintenance instructions; failure to do so could result in damage to the equipment being protected or controlled. Thermostatic service kits may also be used for adapting valves to new service temperatures. Please request a new nameplate when adapting valves to a new service temperature by contacting the facility. AMOT does NOT offer service kits for 8O or 8R Model Thermostatic Valves. In order to properly service an 8O and/or 8R valve please purchase an element and seal kit. Refer to the ordering instructions on page. Service kit model number structure ) Replace ody material (C) and Port connection (D) with KIT-. ) If Special (J) is not blank, please contact the facility.
