The Model 1049 offers the best pilot-operated vent technology on the market today. The unit allows for bubble-tight seat leakage until the pilot starts to exhaust. At that time, the vent starts to open and is fully open at 10% overpressure. Unlike non-pilot operated units that require substantial overpressure in order to obtain full lift. On Model 1049, the blowdown is limited, and the valve reseats at the set point, where the non-pilot-operated units will go below the set point in order to reseat.

The Model 1088 is a valve specifically designed for small tank blanketing applications. It opens and closes automatically as required to maintain a closely controlled blanket pressure. Standard valve material provides added corrosion protection at no additional cost The simple design increases reliability and lowers maintenance cost.
-
The Model 1100 is a stainless steel sanitary vent designed to operate at multiple set points as a breather valve to avoid vacuum or over-pressurization inside a tank or piping system. This unit comes with a true sanitary blanketing connection and is designed so that it can be used with our sanitary blanketing valve; VCI model 1088.

The Model 2100 provides ready access to storage tanks for gauging or obtaining samples. The gauge hatch may also provide additional pressure relief as a supplement for normal or emergency venting. These gauge hatches are intended for use where the fire protection afforded by flame arresters is not considered necessary. Common applications where it is commonly used includes atmospheric and low pressure tanks.
-
The Model 2199 pressure/vacuum relief hatch provides overpressure relief beyond that furnished by the normal pressure vent for atmospheric and low-pressure tanks. The Model 2199 can also be used as a spring-operated conservation vent and tank hatch that provides convenient access for tank cleaning, inspection, and repair.

Cashco’s Model 3200 in-line conservation breather vent is part of the Valve Concepts, Inc. modular vent product line. The Model 3200 can easily be field converted to a vacuum-only vent, a pressure/vacuum vent to the atmosphere, and can either be direct acting or pilot operated. Only Valve Concepts offers complete modularity throughout its complete vent product line.
-
The Model 3300 end-of-line conservation breather vent is part of Valve Concepts, Inc. modular vent product line. The Model 3300 can easily be field converted to an end-of-line pressure/vacuum relief vent with the addition of weather hood components or an in-line pressure/vacuum relief with the addition of pipe away body components.
-
The Model 3600 end-of-line conservation breather vent is part of Valve Concepts, Inc. modular vent product line. The Model 3600 can easily be field converted to a pressure-only vent, a pressure/vacuum vent with pipe away, and can either be direct acting or pilot operated. Only Valve Concepts offers complete modularity throughout its complete vent product line.
-
The Model 3700 manhole and emergency pressure vents provide emergency pressure relief beyond that furnished by the normal pressure vent for atmospheric and low-pressure tanks, as well as providing convenient access for tank cleaning, inspection, and repair. Emergency relief valves provide relief from excessive internal pressure, which an abnormal condition, such as ruptured internal heating coils or an external fire may cause.
-
The Model 3K00 Pressure / Vacuum Vent is designed for use on atmospheric and low-pressure storage tanks where pressure and vacuum relief are required. Weight-loaded pallets in the vent housing allow the intake of air and the escape of vapors as the tank breathes due to thermal changes and product movement in and out of the tank. The pallets open and close to permit in-breathing and out-breathing necessary to maintain the tank pressure within permissible limits to avoid damage to the tank.
-
The Model 4200 pipe-away conservation vent is part of the Valve Concepts, Inc. modular vent product line. The Model 4200 can easily be converted to a vacuum-only vent or end-of-line pressure/vacuum vent and can either be direct-acting or pilot-operated. Only Valve Concepts, Inc. offers complete modularity throughout its complete vent product line.
-
The Model 8700 emergency pressure/vacuum vents provide emergency pressure and vacuum relief beyond that furnished by the normal pressure vent for atmospheric and low-pressure tanks, as well as providing convenient access for tank cleaning, inspection, and repair. The vacuum relief allows the intake of air necessary to maintain the tank pressure within the permissible vacuum limit to avoid damage to the tank.
-
The 8900 Series manway pressure and pressure/vacuum relief vents provide emergency pressure relief beyond that furnished by the normal pressure vent for atmospheric and low-pressure tanks, as well as convenient access for tank cleaning, inspection, and repair. Emergency relief vents provide relief from excessive internal pressure which may be caused by an abnormal condition; such as ruptured internal heating coils, an external fire, a failure of the tank blanketing system, a sudden cooling of the tank or a break in the tank wall.
