4261D Air Intake Shut-off Butterfly Valve
2910
The AMOT 4261D Air Intake Shut-off Butterfly Valve helps to prevent diesel engine runaway. Diesel engine runaway can be a dangerous condition that can harm employees and cause severe damage to various types of equipment every year. A diesel engine will run away, and self destructs on hydrocarbon vapours, even if the engine™s primary source of fuel is taken away. An air intake shut-off valve is a must for diesel engines which also have a possibility of encountering hydrocarbon vapours. The AMOT 4261D Air Intake Shut-off Valve use the best available technology to shut down a runaway diesel by closing off engine intake air.

SVX Hazardous Area Shut Off Valve
9280
The Chalwyn SVX hazardous area, flameproof series of butterfly air intake shutoff valves are ATEX approved for Zone 1, Gas Group IIB, T4 (135°C) or Zone 21 hazardous area applications. The SVX flameproof energize to open valve is designed with a œfail-safe actuation. When power is applied to the solenoid, the valve opens and is held open as long as power is supplied. When power is cut off for any reason, such as the detection of an engine over speed condition or other unsafe engine operating conditions, the valve will close. Features and Benefits ATEX Zone 1, Group IIB, T4 (135°C) or Zone 21 approved Externally switched solenoid Automatic closure on the loss of power Slim-fit 3, 5, and 8 (76mm, 127mm, and 203mm) valve body Basic flange mount with hose adaptors available (1½ to 8 | 38 to 203mm) Valve bodies and discs are PTFE coated rugged anodized aluminium The shaft and mechanisms are stainless steel

2800 Safety Shutdown Device
9290
The AMOT 2800 fuel rack actuator is a safety shutdown device that senses oil pressure or other control pressure. The AMOT 2800 safety shutdown device is typically connected to an engine fuel rack governor or fuel pump stop lever, and should a loss or drop in oil pressure occur below the set point, and it will trip immediately. The 2800 safety shutdown is a snap-acting device monitoring low lubricating oil pressure or other control pressure. An emergency stop handle and a trip pressure adjusting screw are standard. Factory set to trip at 0.7 bar (10 psi) and field adjustable, from 0.35 – 2.8 bar (5-40 psi). A trip lever is installed on a splined shaft and can be clamped in 36 basic positions to facilitate installation in most applications. The lever permits mechanical linkage between the tripping unit and the engine governor control, fuel pump stop lever or other mechanisms. Predrilled holes give a wide range of connection options. A standard Reset Latch is supplied. The Reset Latch locks the trip lever in the œrun position until oil pressure is up to normal operating pressure, then the latch releases, thus arming the device.
