Ручной клапан Installation & Operation

Советы по установке:

Mount the valve securely to a stable surface or panel, ensuring easy access for operation.
Connect air lines to the correct ports (IN, OUT, EXHAUST) as marked on the valve or in the manual.
Use appropriate fittings and thread sealant to ensure leak-free connections.
Ensure the air supply is clean and within the valve’s specified pressure range.
Position the valve so that the actuator (lever, button, knob) can be operated safely and comfortably.

Operation & Maintenance:

Operate actuators smoothly and avoid excessive force.
Periodically check for air leaks and ensure all connections remain tight.
Keep the valve and its actuator mechanism clean and free from obstructions.
For detented valves, ensure the detent mechanism engages positively.
Most manual valves require minimal lubrication if the air supply is appropriately conditioned. Refer to product specifics.

Always de-pressurize the system before installing or performing maintenance on manual valves.

Ручной клапан Вопросы и ответы

When should I choose a manual valve over an automated (e.g., solenoid) valve?

Manual valves are preferred in situations requiring:

Direct Operator Control: When a human operator needs to initiate or stop a pneumatic function directly at the point of use.
Simplicity & Low Cost: For basic on/off or directional control where automation complexity and cost are not justified.
No Electrical Power: In environments where electricity is unavailable, undesirable (e.g., wet areas without proper IP rating), or poses a hazard.
Safety Lockouts: Valves like the VHS series are specifically designed for LOTO (Lockout/Tagout) procedures to safely isolate energy during maintenance.
Ручное управление: As a backup or setup tool for automated systems.

What's the difference between a 3-way (e.g., 3R/4R series) and 2-way manual valve?

The terms refer to the number of ports and flow paths:

2-Way Valve (2/2): Has two ports (inlet and outlet) and two positions (open or closed). It’s a simple on/off valve. Our VHS series lockout valves function as 2-way or 3-way shut-off valves.
3-Way Valve (3/2): Has three ports (typically inlet, outlet/cylinder, and exhaust) and two positions. It’s commonly used to control single-acting cylinders (pressurizing to extend, exhausting to retract via spring) or to select between two different air paths. The “R” in 3R/4R often denotes the number of ports in that specific series convention.
4-Way or 5-Way Valve (e.g., 4R series might be 4/2 or 5/2): Used to control double-acting cylinders, providing air to extend and retract the cylinder. A 4-way valve has four distinct working ports; a 5-way valve has five (often two exhaust ports).

How do I select the correct port size for a manual valve?

Selecting the correct port size is crucial for ensuring adequate airflow to your pneumatic device. Consider:
- Actuator Size: Larger cylinders or tools generally require larger port sizes to achieve desired operating speeds.
- Required Flow Rate (Cv/Kv): The valve’s flow capacity should match or exceed the system’s demand. Undersized valves can cause sluggish performance.
- Tubing/Fitting Size: Match the valve port size to the existing or planned tubing and fitting sizes in your circuit to avoid unnecessary restrictions or adapters.
- System Pressure: While not directly determining port size, it works in conjunction with flow rate.
Product datasheets will list available port sizes (e.g., G1/4, G1/2) and corresponding flow rate data.

What is a "Safety Lockout Valve" like the VHS Series used for?

A Safety Lockout Valve, such as our VHS Series, is a critical safety component used in pneumatic systems. Its primary purpose is to isolate a section of the pneumatic system from the air supply and vent any trapped downstream air pressure. This ensures that machinery or equipment is de-energized and cannot unexpectedly operate during maintenance, servicing, or cleaning.

Key features and uses include:

Energy Isolation: Safely cuts off air supply to a machine or zone.
Venting Residual Pressure: Automatically vents downstream pressure to atmosphere when shut off, preventing stored energy hazards.
Lockable Handle: Allows a padlock to be attached in the “off” (vented) position, complying with LOTO (Lockout/Tagout) safety procedures.
Clear On/Off Indication: Provides a clear visual status of the air supply.

What kind of maintenance do manual valves typically require?

Manual valves are generally robust and require minimal maintenance, especially when used with clean, dry air. However, some periodic checks can ensure long life:

Проверьте наличие утечек: Periodically inspect for any air leakage from ports, seals, or the actuator stem.
Actuator Operation: Ensure the handle, lever, or button moves smoothly and fully engages in its positions (especially for detented types).
Cleanliness: Keep the valve exterior and actuator mechanism free of excessive dirt, grime, or corrosive substances.
Mounting Security: Verify that mounting screws or nuts are still tight.
Lubrication (Rarely Needed): Most modern manual pneumatic valves are designed for non-lube service. If your specific valve requires lubrication (check manual), ensure it’s done with a compatible lubricant.

If a valve becomes difficult to operate or leaks persistently, it may indicate internal seal wear or contamination, and servicing or replacement might be necessary.
