G2FR (Reverse Acting) 2-way Control Valve

G2FR (Reverse Acting) 2-way Control Valve

8984

The Clorius G2FR (reverse acting) 2-way control valve is mainly intended to control cooling systems. The G2FR control valve is used in conjunction with temperature- or pressure differential regulators. As the reverse acting valve is held in a closed position using a built-in spring, the max. differential pressure, ΔpL, against which a valve can close depends on the spring, and when opening the valve, the actuator has to overcome the spring force. See datasheet to find the max. allowable values of ΔpL as well as the max. allowable inlet pressures for opening the valves, p1max for various actuator forces. Design The valve components, spindle, seats and cone, are made of stainless steel. The valve body is made of nodular cast iron EN-GJS-400-15 with flanges drilled according to EN 1092-2. The connection thread for the actuator is G1B ISO 228. The valves are double-seated and designed for tight closure. The leakage rate is less than 0.5% of the full flow (according to VDI/VDE 2174). Function Reverse Acting Without an actuator being connected, the valve is held in a closed position using a spring. With pressure on the spindle, the valve opens. In connection with our actuators, the valves act as œcooling valves, i.e. they open at rising temperatures. The linear characteristic will not cease until the flow has dropped below 4% of the full flow.

G2F 2-way Control Valve (DN100-DN150)

G2F 2-way Control Valve (DN100-DN150)

8991

The Clorius G2F 2-way control valves (DN100…DN150) is designed for use in regulating high-pressure hot water, steam and heat transfer oil. The valves are used in conjunction with temperature or pressure differential regulators for controlling district or central heating plants, industrial processes or marine installations. Design The valve components “ spindle, seats and cone “ are made of stainless steel. The valve body is made of nodular cast iron EN-GJS-400-15 with flanges drilled according to EN 1092-2. The connection thread for the actuator is G1B ISO 228. The valves are double-seated. The leakage rate is less than 0.5% of the full flow (according to VDI/VDE 2174). Function Without the actuator being connected, the valve is held in an open position by means of a spring. 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 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.

Rigsaver SGE Air Shut Off Valve

Rigsaver SGE Air Shut Off Valve

9317

The AMOT Rigsaver SGE air shut off valve is a swing-gate, spring-operated air shut-off valve mounted in the air intake system. It will impede the airflow into the cylinders and positively stop the engine. It can be installed pre- or post-turbo. The Rigsaver shutoff valve can be manually or automatically controlled to respond to a variety of fault or hazard conditions. The AMOT Rigsaver SGE has been used worldwide, providing reliable service on and offshore under adverse conditions associated with locations in the Canadian Arctic, the Gulf of Mexico, the North Sea, the deserts of Africa, the Middle East and the Pacific Rim. Our product's quality meets or exceeds the stringent requirements of our broad customer base, which includes leading engine OEM's. The AMOT Rigsaver SGE air shut off valve will cut off the air supply to a diesel engine, safely bringing the engine to a stop. Installing an air shut-off device protects both personnel and equipment.
