Shoulong Valve
1 / 1
Protects upstream and downstream seats from excessive load for long service life.
Prevents cold transfer to packing and actuator, and ensures stem retention under pressure.
Enhances sealing reliability under extreme low temperatures.
Reduces operating torque for precise control; ISO 5211 mounting allows for easy automation upgrade.
It mechanically anchors the ball at the top and bottom, preventing shifts under line pressure. This reduces seat load, extends service life, and is ideal for high-pressure or large-diameter applications.
It creates a thermal barrier between cold media and the packing/actuator, preventing cold transfer that could cause packing to become brittle or actuators to malfunction.
It prevents the stem from being ejected from the valve body under high pressure, a critical safety design that protects personnel even if packing fails.
Specifically engineered for cryogenic temperatures, it maintains flexibility and sealing integrity where conventional seals might harden and leak.
Yes, the ISO 5211 mounting pad allows for straightforward installation of electric, pneumatic, or hydraulic actuators without body modifications.
Designed for demanding industries like LNG, liquid oxygen, liquid nitrogen, petrochemical processing, and extreme temperature fluid handling.
