3-Way Control Valve

3-WAY CONTROL VALVE – PNEUMATIC ACTUATED OR ELECTRIC ACTUATED –  Amot Model GE and GP

Amot Controls has redesigned and significantly enhanced the G Valve three-way temperature control valve, making it more economic and compact while also reducing the unit weight and installation costs, and at the same time upgrading performance with a 70% increase in flow capability.

A new enhanced control system has also been introduced to further improve this valve. It consists of a new PID process controller with temperature dead band, remote output alarms as standard and logic outputs to drive 25A solid state relays (SSRs) having significantly higher performance than standard relays.

 

Model GP Control Valve – Pneumatic Actuated

The Amot Model GP Valve is a 3-way temperature control valve that provides a high degree of accuracy and repeatability for accurate temperature control. The valves are equally accurate in mixing or diverting applications over a wide range of flow rates.

The thermostatic valve is designed for high vibration service. The GP valves are qualified to Lloyd’s Marine Requirements for shipboard service. These valves can be directly mounted to reciprocating machinery such as compressors or diesel engines without the need of vibration isolation.

The valve can operate with many existing control systems. Amot can also supply either the pneumatic or electro-pneumatic control systems to meet your specific application.

Operation
The valve uses a spring return pneumatic actuator and positioner to control the rotation of the valve in response to an input signal from a pneumatic or electro-pneumatic control system. The pneumatic control system sends a pneumatic signal ranging from 3 to 15 psi to the actuator to correctly position the valve at the desired temperature setting. The pneumatic control system usually consists of a P+I pneumatic controller, sensor and the necessary air supply conditioning equipment. (regulators, filters & waste traps).

Model GE Control Valve – Electric Actuated

The Amot Model GE Valve is a 3-way temperature control valve consisting of a heavy duty rotary valve and a quarter turn electric actuator. Model GE valves provide a high degree of accuracy and repeatability for accurate temperature control.

The valves 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.

Designed for high vibration service, the 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 and seal materials are available for services involving synthetic or fire resistant oils, deionized water and ammonia or freon in oil.

The compact design of the control valve minimizes the installation space required.

Features

• Accurate and Repeatable Temperature Control
• Low Pressure Drop 0.15 to 1.5 PSI
• Selectable  Directions of Flow Control
• Vibration Resistant
• Mount in any Position
• Compact Design
• Nema 4 Weather Proof Construction
• Standard Manual Overide
• Position Indicator
• Sizes 2″ to 16″
• 40 GPM to 8300 GPM

Applications

For Refineries, Chemical Plants & Oil Reproduction:

• Waste Heat Boilers
• Product Coolers
• Product Heaters
• Product Condensers

For Engines, Turbines, Gear Boxes & Heat Exchanges:

• Charge Air Cooling
• Secondary Cooling System
