The three-way solenoid is a valve that opens and closes flow depending upon the electrical state of the coil. It maybe used directly on smaller valves (e.g. OCV Model 115-1), or in conjunction with a high-capacity auxiliary pilot to make larger valves operate faster (e.g. OCV Model 115-4). MODEL SHOWN: ASC0 8320A170 Provides On/Off (Open/Close)
The four-way solenoid is a valve that shifts position depending upon the electrical state of the coil. The body is equipped with four ports; Supply, Exhaust and two Operating Ports. In one position the solenoid pressures one operating port while venting the other. In the other position the pressurization/venting of the two ports is reversed.
The A224 is an auxiliary pilot operated by a smaller ported control such as a float, altitude or solenoid pilot. Its purpose is to provide accelerated opening and closing action of the main valve. It is typically installed with its Inlet port connected to main valve inlet, its Exhaust port connected to main valve outlet,
The Model 815 Float Pilot is two-way, rotary-disc control designed primarily for fuel service with floating roof tanks. It may also be used anywhere access to the tank interior is restricted or impossible. Suitable for both modulating and on-off service. The 815 pilot operates the main valve directly on OCV Series 8103 Float Valves, and
The 814 is a float-actuated, three-port pilot that controls the opening and closing of the main valve. The float rides freely on a vertical rod, with adjustable stop collars above and below. When the float reaches the upper stop, it moves the linkage up, rotating the pilot to close the main valve. When the float
The Model 813 Float Pilot is two-way, rotary-disc design suitable for both modulating and on-off service. In modulating service, the 813 can be configured for either flow into the tank (rising float closes main valve) or out of the tank (rising float opens main valve). In either, the valve maintains a constant level. Positive shut-off
The Model 812 Float Pilot is two-way, rotary-disc design suitable for both modulating and on-off service. In modulating service, the 812 can be configured for either flow into the tank (rising float closes main valve) or out of the tank (rising float opens main valve). In either, the valve maintains a constant level. Positive shut-off
The 3600 is an auxiliary pilot operated by a smaller ported control such as a float, altitude or solenoid pilot. Its purpose is to provide accelerated opening and closing action of the main valve. It is typically installed with its #3 port connected to main valve inlet, its #2 port connected to main valve outlet,
The 3300 senses tank head (pressure) under its diaphragm and balances it against an adjustable spring load (high level shut-off setting). When tank head is below the setting, the internal mechanism shifts to route the pressure on the main valve diaphragm chamber to atmosphere (bonnet port > vent port), allowing the main valve to open
The Model 2450 is a two-way, normally open pilot that senses the differential pressure across an orifice plate; high pressure under its diaphragm and low pressure above the diaphragm. The orifice plate differential is proportional to the flow rate through it. The pilot balances the differential against an adjustable spring load. An increase in differential,
