AMOT Model G Valve – Pneumatic and Electric:
AMOT G valves are 3-way rotary control valves consisting of a heavy duty rotary valve and either a quarter turn electric or pneumatic actuator. The valves provide a high degree
of accuracy and repeatability for accurate temperature control and are equally accurate in mixing or diverting service over a wide flow range. The heavy duty rotor design provides tight temperature control without high maintenance requirements.
The system is available in three standard control configurations: electric; pneumatic; and electro-pneumatic, offering flexibility for most requirements. Designed for high vibration service, the AMOT G valves are qualified to Lloyd’s Marine Requirements for shipboard service. Valves can be directly mounted to reciprocating machinery, such as diesel engines, without vibration isolation.
The heavy duty actuators are specially reinforced to provide vibration resistance. The standard valves are suitable for a variety of fluids such as water, water/glycol, sea water, lubricating and hydraulic oils. Optional body materials are available for services involving synthetic or fire resistant oils, deionized water and ammonia or freon in oil.
For engines, turbines, gearboxes
and heat exchangers:
- Charge air cooling
- Secondary cooling systems
- Fuel and lube oil preheating
- Engine jacket water
For refineries, chemical plants
and oil reproduction:
- Waste heat boilers
- Product coolers
- Product heaters
- Product condenser
- Ease of integration – valve size matches
pipe size, resulting in reduced installation
time and installation costs
- Flexible design – ports can be configured
to suit installation
- Low pressure drop – compared to other valve
- Small physical size
- Hand wheel allows manual adjustment of valve
(optional on pneumatic valve) – simplified set
up and maintenance
AMOT Model G 3-way rotary control valves provide a high degree of accuracy for precise temperature control in both mixing and diverting applications. If you experience long warm-up times, excessive white smoke coming from the exhaust, or difficulty regulating fluid temperatures at idle, replace your thermostatic valve with an externally-actuated AMOT Model G without the need for piping modifications. Models include GEF, GPD, and GG.
In addition to the standard valve, AMOT offers two Low Leak Model G options: ANSI Class II (0.5% leakage rate) and ANSI Class IV (0.01% leakage rate). Contact us for more details.
The heavy-duty, compact design fits in cramped spaces and withstands high vibration applications to minimize stem leaks and actuator board failures.
The external temperature sensing probe enables more precise, more responsive temperature control. With the Model G, you can maintain a temperature setting to within +/- 1oF.
Our unique design allows ports to be configured to suit any installation requirement. The Model G can operate equally well as a stand-alone valve or as part of a complete control system. In addition, we offer a variety of models, sizes, actuator types, communication protocols, and other options to help you specify exactly what you need.
The AMOT Model G valve has over 25 years of proven performance in Marine, Power Generation, and Oil & Gas applications.
