Level Gauge Valves

• Available up to 3″ full bore (other sizes available on request)
• Floating Ball design with robust lever operation
• Flanged connections in accordance with ASME B16.5
• Integral vent valve with threaded outlet connection
• Additional flushing valves after second isolate valve to allow cleaning of diaphragm seal without removal of the transmitter.

The single-piece body with threaded end inserts provides the most compact overall length and reduces potential leak points to an absolute minimum.
Valves are available with full bore sizes in accordance with API 6D, ensuring the full area of the diaphragm is exposed to process pressure for accurate level measurement.
Various bleed valve options and connections are available in line with customer requirements.
The floating ball construction ensures maximum weight and space savings whilst providing reliable and safe isolation up to and including ASME Class 2500.
Typically supplied with two isolating ball valves to allow thorough flushing of the diaphragm seal surface, thus ensuring accurate level measurement and easy calibration of the transmitter.
