Lockable Pneumatic Valves
Lockable valve size: 0-1-2 G1/4″ G3/4″. The lockable valve is a 3-way 2-position manual valve. In the closed position it enables discharge of the downstream system of the air preparation equipment. An optional lock (supplied upon request) allows the user not to pressurise the system accidentally.
Lockable pneumatic valves from MasterMac2000 provide reliable flow control and enhanced safety functionality for automated industrial pneumatic systems.
Versatile Flow Control 
As a three-way, two-position manual valve, the lockable pneumatic valve directs compressed air with precision to pneumatic tools, actuators and other downstream components. Its versatile 3-port configuration allows for switching between pressurising connected pneumatic devices or isolating their air supply with a simple twist of the robust metal handle. Operators can control airflow for active work cycles or safely discharge pressure for maintenance tasks.
Rigid Safety Interlocks
An integral feature of the Lockable Pneumatic Valve is its patented lockable design. The valve body includes a reinforced adapter that securely fastens the handle in the closed position when engaged. Compatible padlocks or similar locking mechanisms prevent unintended opening and ensure isolated discharge of residual compressed air pressure. This interlock function provides valuable additional safety during machinery repairs or process adjustments when accident
al pressurisation must be avoided.
Industrial-Grade Durability
Built for continuous usage in demanding manufacturing and process environments, the all-metal construction of our lockable valves withstand vibration and temperature fluctuations. The die-cast aluminium body housing protects smoothly operating ball-style internal components from corrosion and damage. This heavy-duty build quality delivers reliability and extended operational lifetimes, reducing cost of ownership.
Customised Solutions
MasterMac2000 offers lockable valves in industry-standard port sizes 0 (G1/4 inch), 1 (G1/4 inch) and 2 (G3/4 inch) providing installation compatibility. Rated for operating pressures up to 16 bar as standard, higher pressure versions can be specified for spe
cial applications. Customers can also select optimised valve configurations matched to their unique flow and pressure requirements, machine coupling specifications and adherence to relevant safety protocols.
Precise Flow Control
Ball-style internal components control compressed airflow with minimal pressure drop, maintaining pressure levels to power tools and actuators precisely as required. Pressure regulation is smooth and efficient, maximising productivity. Standard and customizable pressure ratings cater to a broad range of industrial automation applications.
