Characteristics

Fully welded body structure to avoid leakage.

Since the seat is made of a carbonized Teflon seal ring and a spring, it is highly adaptable to changes in pressure and temperature, and does not cause any leakage within the marked pressure and temperature range.

30 years of effective service life, maintenance-free, and the same life as the pipeline.

A proprietary valve seat (multiple seal construction) guarantees zero leakage.

The operator does not need to enter the well, and the T-handle can be used on the well for convenience and safety.

Pressure prefabricated insulation type valves can be provided to effectively avoid the lack of on-site insulation conditions.

The discharge valve is a safety device in the pipeline transportation. When the internal pressure of the pipeline exceeds a certain value, a part of the medium in the pipeline can be discharged through the discharge valve, thereby reducing the internal pressure of the pipeline.
