Classification of Ball Valve Lockouts

 Ball valve lockouts are devices made of high-strength polypropylene plastic. They are fully insulated and offer excellent resistance to solvents and other chemical substances, along with outstanding impact resistance and wear durability.

Available colors include red, yellow, blue, and green.

Double-Arm Universal Ball Valve Lockout
The newly designed WELKEN double-arm universal ball valve lockout is made of industrial-grade high-strength resin and reinforced steel. Its advanced upper trapezoidal tooth design enhances the grip and strength on the valve handle.

The gear engagement of the rotating arms is tighter, improving safety performance. The newly designed two-stage adjustable swing arm length allows for more precise and convenient operation. It also features strong impact resistance and superior chemical resistance, representing one of the most advanced double-arm universal ball valve lockouts in the world.

Single-Arm Universal Ball Valve Lockout
The single-arm universal ball valve lockout is also constructed from industrial-grade high-strength resin and reinforced steel. The advanced upper trapezoidal tooth design improves the grip and strength on the valve handle.

The tighter meshing of the rotating arm enhances safety performance. The newly designed two-stage adjustable swing arm length provides greater precision and convenience. It offers excellent impact resistance and outstanding chemical resistance, making it one of the most advanced single-arm universal ball valve lockouts available.

Specifications

  • Temperature range: -40°C to 180°C
  • Suitable handle width: 19 mm – 46 mm
  • Suitable handle thickness: up to 25 mm
  • Rotating arm length: 170 mm
  • Adjustable range of rotating arm: 55 mm
  • Total weight: 720 g

Ball Valve Lockout Selection Process

  1. Determine the total number of ball valves at the factory.
  2. Identify the sizes of the ball valves and count the quantity in each size range.
  3. Determine the locking frequency for ball valves of each size in the factory.
  4. Determine the required number of lockouts for straight ball valves and ball valves with stop arms.

Insulated Padlocks — A Solid Guarantee of Safety and Protection

Image
In modern society, as awareness of safety and protection continues to grow, the use of various safety devices has become increasingly widespread. Padlocks , as a common security tool, are widely used in homes, warehouses, factories, and other locations, serving multiple functions such as safeguarding property, preventing theft, and restricting unauthorized access. However, in certain special environments, ordinary padlocks are not sufficient—particularly in fields involving electrical installations and high-voltage power sources. Ordinary metal padlocks may pose serious risks if they come into contact with electricity, potentially causing severe electric shock accidents. To effectively address this problem, insulated padlocks were developed, becoming an essential tool for ensuring the safety of electrical facilities. Insulated Padlocks The core advantage of an insulated padlock lies in its electrical insulation properties. Traditional padlocks are usually made from metal, which is hi...

Correct Way to Open a Magnetic Valve Lock

Image
At present, many households are equipped with radiators. Some radiators are installed with magnetic valve locks . If a common issue occurs, how should it be handled? What should be noted when installing a magnetic anti-theft valve lock? Below is a detailed explanation. I. How to Open a Magnetic Valve Lock with a Radiator? Do not attempt to open a magnetic radiator valve lock casually. It generally requires a matching key, which is usually kept by professionals from the heating supply company. If repairs are needed, you should contact the on-site service personnel—they will have the corresponding key. The key has a small red dot that should align with the dot on the valve. Before unlocking, press the key cap so that it pops up into the open position. Then pull the key cap upward and use a wrench to turn the lever. You will notice the indicator rod on the key changes its reading: for example, from 0 to 1 , where 0 means closed and 1 means open . If you want to open a mag...

Factories Introduce Branded Safety Lock Equipment to Ensure Safety

Image
 With the continuous advancement of industrialization, factory production is expanding in scale, and the variety and quantity of equipment are increasing. However, this growth also brings a rise in safety risks. To ensure the safety of workers and equipment, introducing the latest top-brand safety interlock devices has become an inevitable choice for factories. Safety interlock devices combine electronic technology with mechanical principles to provide multiple safety protection functions during equipment operation. They can use sensors to detect the operating status of equipment, and once an abnormal situation is detected, the device will immediately cut off the power supply to prevent accidents. These devices not only protect workers but also safeguard the equipment itself, extending its service life and improving production efficiency. In factory operations, various hazards often exist, such as high temperatures, high pressure, and high-speed machinery. Once an accident occ...
