VHK3A-08F-08F: Manual Operation, Reliable Switching! 3-Port Manual Rotary Valve Empowers Fluid Path Control

In applications requiring manual switching of fluid paths, system commissioning, or emergency intervention, a reliable and intuitive manual valve is essential. The VHK3A-08F-08F is a 3-port manual rotary valve (plug valve or rotary spool valve). It switches between different flow paths by rotating the valve core, and with its simple operation, reliable sealing, and compact design, it serves as an ideal choice for manual control in pneumatic, hydraulic, and low-pressure fluid systems.Core Product Advantages

• Manual Rotary OperationOperated by turning a handle or knob to actuate the valve core. The operation is simple and intuitive, with clear tactile feedback and distinct position indication.
• 3-Port Flow Path SwitchingFeatures three ports (e.g., P: Pressure supply, A/B: Work ports), enabling various flow path configurations such as P→A, P→B, or A/B→Exhaust to meet different control logic requirements.
• Reliable Sealing & Minimal LeakageThe valve core and body are precision-matched. Sealing materials are oil-resistant and wear-resistant NBR or FKM, ensuring reliable switching and low internal leakage.
• Compact Structure & Easy InstallationCompact and lightweight design. Offers panel mounting or direct inline piping installation options, saving space and enabling easy integration.
• Visual Position IndicationClear flow direction markings on the valve stem or handle allow for intuitive identification of the current flow path status.

Typical Application Scenarios

• System Commissioning & Venting:​ Used for initial system venting, manual debugging, or function selection in pneumatic/hydraulic systems.
• Mode Switching:​ Manual/automatic mode selection or function switching on equipment.
• Emergency Shut-off:​ Serves as a manual shut-off valve to isolate the air/fluid supply in emergencies.
• Experimental Setups:​ For manual flow path switching and control in laboratory apparatus.

Technical Parameters (Typical Values)

• Valve Function:​ 3-port, 2-position; 3-port, 3-position, etc. (Specific function needs verification against model code)
• Port Size:​ G1/8″ (08F likely indicates port specification)
• Operating Pressure Range:​ 0.1 ~ 1.0 MPa
• Temperature Range:​ -5℃ ~ +80℃ (Medium temperature)
• Operation Mode:​ Manual rotation

SummaryThe VHK3A-08F-08F manual valve is the “manual switching expert” in fluid control. Through its simple and reliable rotary operation, it provides flexible control over fluid paths, offering a direct and dependable means for system debugging, mode switching, and safety intervention.Choosing the VHK3A-08F-08F means selecting an intuitive, reliable, and flexible manual control solution!
