Special ball valves E'NERPRED-YaRDOS With leak control, etc.

Underground ball valves. This design provides for the construction of a crane with an elongated rod of a given length mounted in bearings. The drainage tube is brought to the crane control level. The crane can be operated manually or with a drive. The outer surface of the crane is covered with an anti-corrosion protective coating that protects against mechanical damage and chemical effects of groundwater.

Ball valves with leakage control allow not only to monitor the condition of the seals, but also to drain the remnants of the medium from the crane body, both in the open and closed position of the plug, since the valve cavity in the extreme positions is cut off from the working medium. The cranes can be supplied either with a plug or with an additional shut-off valve.

Ball valves with antistatic protection. Constant electrical contact of the rotating parts of the crane (spindle, plug) with the body using a spring-loaded ball. Guarantees protection against the formation of static electricity.

Ball valves with sealant pumping. The taps have channels for entering the sealant. This provides a quick and easy way to restore the tightness of the seal on the spherical plug and the spindle of the ball valve.

Quick-closing ball valves are equipped with high-speed electric drives that allow both rapid opening and rapid closing of the working medium flow. The response time is up to 1 second. Ball valves can also be equipped with actuators with a closing/opening time from 3 to 60 seconds. Cranes can be equipped with an emergency protection unit to activate the drive even in the event of a power outage.
