Pneumatic Angle Seat Valves
Tests have proven that the Jinke angle seat valve has a service life exceeding one million cycles.
KINKO Pneumatic Angle Seat Valve
The valve body is constructed from CF8/CF8M stainless steel and offers a variety of end connection options (welded, threaded, clamped, or flanged). It is suitable for a wide temperature range of -20°C to +180°C. When installed in a flow-closing configuration, it generates no water hammer effect.
Behind Every Solution:
- Service life exceeding 1 million cycles
- Class VI Zero Leakage
- Temperature resistance: 180°C
- IP68 Protection

Design Principles
Why are KINKO angle seat valves so durable?
- The closing mechanism of the Jinke angle seat valve consists of a valve plug fitted with a seal, which seats tightly against the valve seat. By controlling the position of the valve plug, the flow rate can be regulated according to the valve's opening degree.
- The pneumatic actuator connects to the valve plug via a piston rod and operates independently of the working medium. Dynamic sealing of the piston rod is achieved through self-adjusting packing, ensuring long-term, leak-free operation.
- The angle seat valve permits flow in both directions. For liquid applications, it is strongly recommended that the flow direction be configured to close against the seat (flow entering from beneath the seat) to prevent water hammer effects and pressure spikes.

FAQ
What is the maximum temperature rating for KINKO angle seat valves?
Standard models handle media temperatures from -20°C to +180°C with PTFE seals. High-temperature versions with special seals are available up to 300°C. For steam above 150°C, remote mounting of solenoid pilot valve is recommended to protect the solenoid from heat.
How does the angle seat valve prevent water hammer?
When installed with flow entering from below the seat (closing against the plug), the valve closes smoothly without creating pressure spikes. This flow direction allows the plug to close with the flow, eliminating the water hammer effect common in other valve types.
What is the leakage class of KINKO angle seat valves?
KINKO angle seat valves achieve Class VI zero leakage, the highest leakage class per IEC 60534-4 standards. This ensures bubble-tight shut-off for critical applications such as sterile processing, steam systems, and corrosive media handling.
Can angle seat valves be used in both directions?
Yes, angle seat valves support bi-directional flow. However, for liquid media, the recommended installation is flow entering from below the seat (closing against the plug) to prevent water hammer. For gas and steam, flow direction is less critical.
What is the expected cycle life of KINKO angle seat valves?
KINKO angle seat valves deliver over 1 million cycles in continuous operation. With self-adjusting PTFE seals and maintenance-free actuators, they are engineered for 24/7 industrial operations where frequent cycling is required.
