The ultra-thin ball valve is a pipeline control device with a wafer-type structure, suitable for media including water, steam, oil, nitric acid, acetic acid, oxidizing media, and urea. Its operating temperature range is -29~180℃ (reinforced PTFE seal) to -29~300℃ (opposite polystyrene seal), nominal pressure covers PN1.6~6.4MPa, and nominal diameter is DN15~200mm. It conforms to international standards such as DIN EN558-2005 and API 6D.
This valve features an integral cast valve body and a resilient sealing structure, characterized by short structural length, light weight (only 50% of ordinary ball valves), material savings, and convenient installation. Equipped with a fire-resistant structure, it maintains reliable sealing during fires and supports optional anti-static devices and a 90° perforated locking function. Its ultra-thin design is suitable for dense pipeline installations and is widely used in the petroleum, chemical, and pharmaceutical industries for media shut-off and flow regulation.

ultra-thin ball valve Structural Design
Jacket Connection
The ultra-thin ball valve adopts a wafer-type structure, directly connecting to two pipe flanges via double-ended bolts, eliminating the need for additional flange gaskets. This design shortens the valve body length by 40%-60% and reduces weight by 30%-50% compared to traditional ball valves, significantly saving pipeline layout space and reducing material costs. For example, the structural length of a DN50 ultra-thin ball valve can be reduced to less than 100mm, while traditional ball valves typically require more than 160mm.
Ultra-thin Valve Body and Optimized Flow Channel
The valve body uses a disc-shaped valve plate installed along the pipe diameter, with a straight-through flow channel to reduce media flow resistance. The ball surface is precision ground to Ra≤0.4μm to reduce opening and closing friction; the metal sealing surface uses hard alloy welding or spraying processes to improve wear resistance and high-temperature resistance. Some models integrate an IoT module for remote monitoring and fault early warning.
ultra-thin ball valve Performance Characteristics
Dual Sealing Technology
Elastic Seal: Utilizes reinforced polytetrafluoroethylene (PTFE, temperature resistance -29℃~180℃) or para-polystyrene (PPL, temperature resistance -29℃~300℃), achieving low-pressure sealing through a spring preload device, with a sealing rating of ANSI Class VI zero leakage.
Metal Seal: Through a wedge-shaped closure principle and automatic compensation structure, it is suitable for high-temperature conditions (≤300℃), with a lifespan more than 30% longer than the elastic seal. The metal seal type can withstand temperatures up to 300℃, while the elastic seal type, through modified materials (such as PPL), can be extended to 250℃, suitable for steam, hot oil, and other conditions.
High Pressure Resistance and Corrosion Resistance
Valve body materials include stainless steel (304/316L), carbon steel (WCB), and alloy steel, with integral casting or forging processes ensuring pressure resistance. The nominal pressure ranges from PN1.6 to 6.4 MPa, suitable for medium and low pressure applications. It features a full-bore design with a flow resistance coefficient ≤0.1, and a flow coefficient (Cv value) 20%-30% higher than gate valves.
Fast Opening and Closing with Low Resistance
The ball rotates 0°-90° around its axis. When rotated to 90°, the valve is fully open with minimal resistance to medium flow; when rotated to 0°, the valve is closed, cutting off medium flow. This 90° rapid opening and closing method reduces fluid flow resistance, improves operational efficiency, and has a response time ≤0.5 seconds.
ultra-thin ball valve Applications:
Petrochemical Industry
Catalytic Cracking Units: Controls oil flow, replacing traditional gate valves, reducing medium retention and corrosion.
Sulfur-to-Acid Systems: Used for gas pipeline regulation in sulfur combustion, conversion, and dry absorption sections, resistant to high temperatures (≤300℃) and corrosion from sulfur-containing media.
Reverse Osmosis Systems: Regulates high-pressure water flow; the elastic sealing structure adapts to frequent opening and closing, with a lifespan exceeding 100,000 cycles.
Power and Metallurgical Industries
Thermal Power Plants: Regulate steam flow and pressure to ensure stable generator operation.
Blast Furnace Cooling Wall Piping: Utilizes top-mounted ultra-thin wear-resistant ball valves, suitable for fluid control systems with dense valve installations, offering twice the wear resistance of ordinary valves.
Sanitary and Environmental Applications
Food Processing and Pharmaceutical Industries: Employs 316L stainless steel valve bodies and PTFE seals, compliant with FDA standards, for liquid flow control to prevent media contamination.
Wastewater Treatment Systems: Pneumatically driven models quickly cut off water flow with a response time ≤0.3 seconds, ensuring system safety.
Automated Production Lines
Supports manual, pneumatic (e.g., DA/SR series actuators), and electric (angular stroke electric actuators) drive methods. Pneumatic/electric models connect directly to the actuator for remote automated control. Some models offer optional anti-static devices, fire-resistant structures (maintaining sealing during fires), and 90° perforated positioning locking function (preventing misoperation).
