NEW: shut-off valve by Johnson Electric

- Lowest current & energy consumptions

- Highest reliability against gas impurity

- Low pressure drop for improved gas grid efficiency

- Global leader in gas shut-off valve technology

The GML gas shut-off valve is developed for small residential gas meters. This linear valve utilizes the industry’s safest DC motor technology. The valve is operated by an extremely low energy motor to deliver the highest level of intrinsic safety. The GML valve is designed with an aerodynamic geometry to minimize flow resistance, resulting in extremely low pressure drop for improved gas grid efficiency. Gas shut-off valves must meet the ATEX safety requirements utilizing motors that comply with the IEC 60079-11: 2012-06 intrinsic safety standard for gas group IIA and IIB. The traditional industry practice has been to add a protection circuit with several diodes to reduce the available energy below the specified safety limit. Johnson Electric has developed a new DC motor with a natural energy level far below the specified safety level to completely remove the need for this protection circuit. This eliminates any electronic component failure risk and ensures 100% safe operation.
