● The valve body, made from high-quality materials, includes a ball test fitting and has its middle flane and neck bolted together.
● The valve seat has a single-piston effect for both upstream and downstream flow and features a Double Block and Bleed (DBB) function.
● Between the valve seat and the ball, there are three types of seals: a traditional soft seal, a triangular ring seal, and a hard seal.
● The valve stem includes safety features to prevent it from being ejected if operated improperly.
● The valve is equipped with devices to enhance fire safety and prevent static buildup.
● Emergency sealant injection ports are available for the valve seat seal and stem seal. These are used for repairs in case of leakage, and each port has a grease valve and a check valve.
● The valve has both drainage and venting ports. The drain valve is at the bottom for emptying and venting the cavity, and the vent valve is at the top for cleaning.
● This valve is compatible with various types of actuators, including manual, electric, and hydraulic.
● Valves with welded ends can have their materials adjusted to match the pipeline, ensuring proper welding. Sleeve extensions prevent interference with sealing during welding.
● Underground valves have extended stems to make above-ground operation possible, with accessible grease, drainage, and venting facilities. The stem height is customizable.

Flat gate valve is a type of slide valve that utilizes parallel gate plates as its closing mechanism. These plates are equipped with a spreading mechanism to enhance functionality. The force pressing the plates against the valve seat is regulated by the medium pressure acting on either a floating gate plate or a floating valve seat. In dual gate flat gate valves, the inter-plate spreading mechanism provides additional pressing force. This valve is designed with innovative features including low operating torque, rapid actuation, minimal vibration, extended operational life, and enhanced safety. It is mainly used for the isolation or venting of gases and liquids in pipeline systems.
The “Double Block and Bleed Isolation Philosophy” requires two in-line isolation valves and a bleed valve, used to drain or vent trapped fluid between the two closure elements in order to safely isolate safely the downstream pipe. This feature can be achieved with one single valves c/w a bleed port between the obturators.
RAYS pigvalve is a high-performance ball valve designed for severe industrial environments, featuring multifunctionality aimed at optimizing pipeline cleaning and maintenance. This valve facilitates the movement of pipeline pigs to effectively remove scale, deposits, and other impurities, maintaining cleanliness and flow efficiency in pipelines.
