online pressure balance plug valve

The inverted pressure balance lubricated plug valve is according to ansi product structural features. this kind of valve is applicable to the cutting and connection of pipelines medium as widely used in various industries such as petroleum, chemical industry, pharmacy, chemical fertilizer, power industry etc.
Design details: the pressure balanced system ensures line pressure acts on the plug to reduce the valve torque and avoid the possibility of plug seizure, even after a prolonged time in the open or closed position. periodic lubricant injection, and seat adjustment, can be carried out when the plug valve is under full pressure.
Pressure balancing system: for maintaining pressure equalization between plug port and bottom of the plug, and for ensuring the pressure above the plug being the same or greater than in the plug port, the valve’s pressure balancing system design is available; applications and industries. gas flow throttling; chemical service applications; natural gas
• increased uptime due to pressure-balanced plug, which ensures predictable torque, even under high differential, vibration and thermal cycling. • reliable performance in hostile environments provided by the anti-friction coating weather seal that provides superior corrosion resistance.
