● Low Torque Floating Seat: The valve uses a floating seat with O-ring seals for easy and efficient bidirectional sealing. It requires only half the usual operating torque, making it easy to open and close.
● Dual PTFE and Metal Seals: The seat incorporates a PTFE sealing ring for dual protection with both PTFE-to-metal and metal-to-metal sealing capabilities. It also helps clean debris from the gate.
● Grease Injection for Sealing: Equipped with a grease valve, the valve allows grease to be injected directly to the seal, achieving zero leakage.
● Flow Guiding Hole Design: The gate includes guiding holes to protect the sealing surface from media erosion, ensuring a perfect seal at all times.
● Low Flow Resistance and Pigging Capability: With a straight and smooth channel when fully open, the valve offers minimal flow resistance and supports pipeline pigging.
● Easy Maintenance and Low Leakage: Features a self-sealing packing structure that requires minimal adjustment and has an auxiliary sealing grease injection for guaranteed zero leakage.
● Self-Relieving Seat: Automatically relieves high pressure inside the valve when closed for added safety.
● All-Weather Actuator: Comes with fully enclosed, weather-resistant actuators suitable for all conditions.
● Position Indicator: Includes an indicator to show whether the valve is open or closed.
● Reliable Seat Design: Features a dual soft seal structure and multiple sealing rings for enhanced reliability.

The Side Entry Cryogenic Floating Ball Valve is specially designed for deep cryogenic media (such as LNG, liquid nitrogen, liquid oxygen, etc.) applications. It adopts a unique side-mounted structure to ensure stable operation in extreme low-temperature environments below -196°C~+150°C. The valve body is made of high-quality stainless steel or special alloy materials, combined with precise processing techniques, achieving zero leakage and long service life under ultra-low temperature conditions. It is widely used in liquefied natural gas, air separation equipment, chemical and energy fields, and is a reliable choice for fluid control in harsh conditions.
RAYS single driving double ball valve is a special ball valve design, which combines two ball valves together, but is operated by only one drive device. This design is usually used in situations where two parallel pipelines need to be controlled or isolated at the same time. The design and application of single drive double ball valves need to consider specific process requirements and operating conditions to ensure its long-term stable operation and system safety.
RAYS pig valve 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.
