Valve TypesPush button self closing valves
Push-button operation
Except when a reading is being taken, the gauge is permanently isolated from the contents of the tank. To take a reading the spring-loaded valve is opened by pressing a push-button. When released, the connection between the tank and gauge is automatically resealed.
Safe from external damage
Due to the design of the push-button isolation valve, no amount of damage to the gauge or external fittings on the tanks can break the liquid seals. In such an event the fluid cannot escape.
Closed circuit design
The closed circuit design penetrates the tank wall at both top and bottom connections. The options for the top connection are either a push-button self-closing valve or valveless tank return.
Open circuit design
This is only allowable when it is possible for the gauge column to extend above the top of the tank by at least 100 mm. The upper end of the gauge can be supplied with an automatic safety vent valves or, alternatively, a pipe union connection. The automatic safety vent will allow air to pass, but will seal against a liquid level. In the case of the pipe union connection design, a 10 mm o/d steel vent pipe is returned to the tanks or into the tank vent pipe.
Hydraulic actuation
Hydraulic actuation can be supplied as an optional extra. This is designed to enable both push-button valves to be operated at the same time. Recommend for tall gauges where it would otherwise be difficult to operate the upper and lower push-button valves simultaneously.
Graduation
Where a measure of the precise storage volume is required, an engraved scale plate can be provided marked with the capacity units.
Durable Construction
Liquid-level indicators are built to withstand harsh environments. Look for models with corrosion-resistant materials, leak-proof seals, and robust designs for long-lasting performance.
