● 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.

RAYS manufactures high-quality fully welded ball valves, forged from premium materials with side-mounted balls. The valves are available in two designs: cylindrical and spherical fully welded bodies. RAYS is particularly known for its cylindrical valve bodies.
RAYS' rising stem ball valve is designed to operate without friction between the ball and the seat during opening and to achieve zero leakage when closed. This makes it well-suited for demanding conditions. The valve is made entirely of metal and is fire-resistant, capable of functioning in extreme temperatures ranging from -196°C (320.8°F) to 538°C (1000.4°F). It can handle media with particulates like sand and short fibers, and meets NACE standards for corrosion resistance, ensuring it can resist sulfide stress cracking in harsh environments. The valve also features a self-cleaning mechanism. When the ball is tilted away from the seat, the fluid flows 360° around the ball's sealing surface, effectively removing any debris. This prevents damage from high-speed fluid flows and keeps the sealing area clean. The rising stem ball valve is ideal for various applications including exhaust, fluid transfer, pipeline isolation, bypass, product segmentation, and emergency shutdowns, particularly where high switching frequencies and zero leakage in high temperatures are required.
There are two main types of forged steel check valves: forged steel swing check valves and forged steel lift check valves. The quality of forged steel parts is higher than that of cast steel parts, and they can withstand large impact forces. Their plasticity, toughness, and other mechanical properties are also higher than those of cast steel parts.
