The Clorius pressure-balanced G1FB 2-way control valve is designed for regulating hot water, steam and hot oil systems. Balanced valves are used in installations where the system pressure necessitates a closing force greater than available in the actuator programme for a standard single-seated valve, and where the leakage rate for a double-seated valve is unacceptable. The G1FB 2-way control valve is used in conjunction with Clorius temperature- or pressure differential regulators for controlling industrial processes, district or central heating plants or marine installations. DESIGN The valve components – spindle, seat, cone and bellow – are made of stainless steel. The bellows for balancing the pressure are fitted on the valve spindle, which reduces the force necessary for closing the valve, as the upstream pressure of the medium through the hollow valve spindle acts outside and the pressure after the valve acts inside the bellow system. The valve body is made of nodular cast iron EN-GJS-400-15 with flanges drilled according to EN 1092-2. The thread for the actuator connection is G1B ISO 228. The valves are single-seated. The leakage rate is less than 0.05% of the full flow (according to VDI/VDE 2174). FUNCTION Without an actuator being connected, the valve is held in an open position using a spring and the bellow system. With pressure on the spindle, the valve will close. In connection with our thermostats, pneumatic or electric actuators, the valves will close at rising temperatures. For cooling circuits, the valve can be used in conjunction with a reverse acting electric actuator. Alternatively, a reverse acting double-seated valve can be used with our self-acting thermostats. The quadratic characteristic will not cease until the flow has dropped below 4% of the full flow.

The AMOT FET temperature and filter manifolds are fully automatic, 3-way fluid temperature controllers for diverting applications. The FET diverting filterstat is available in 1 ¼ and 1 ½ sizes and settings to fill many fluid temperature control requirements. The FET has a compact design and low installation cost, and flexible spin-on filter manifold, allowing customers to use filter size of their choice. As with other AMOT thermostatic valves, temperature and filter manifold uses fully enclosed, factory-set temperature element assemblies which provide tamper-proof operation. It is field replaceable and is available with temperature settings from 49°C to 113°C (120°F to 235°F). To change a valve setting, it is necessary to exchange the temperature element assembly.
