- Operating Pressure: Up to 1500 psi (per ASME B16.34)
- Weight: Usually lighter than the penstock, with a weight ranging from 0.3 kg to 0.8 kg, depending on the materials and design.
Operation and Use:
Gate and Globe valves are used in industrial plants to control liquid and gas flows.
Gate valve (gate valve):
- The MK Gate gate valve is used to fully open or close the flow of a fluid in a piping system. The operation is simple: the disc (or wedge ) moves along the axis of the valve thanks to a crank or a lever, allowing or blocking the passage of the fluid. These valves are ideal for applications where total closure is required.
- Typical use: hydraulic systems, oil pipelines, gas pipelines and in industrial fluid distribution systems.
Globe valve:
- The Globe MK valve is designed to regulate the flow of a fluid precisely. The valve body has a distinctive shape that allows for greater adjustment capacity than the gate valve, making it ideal for applications where fine flow regulation is required.
- Typical use: heating, refrigeration, water treatment and chemical applications.
Main Components of MK Valves:
- Valve Body: Made of steel, bronze or stainless steel depending on the specific model, it offers resistance and durability.
- Disc: The closing disc (for the Gate valve ) is designed to allow hermetic closure of the flow.
- Gaskets: High quality gaskets made of resistant materials such as graphite or PTFE, used to prevent leaks and ensure tightness.
- Bottom: The base of the valve is designed to ensure stability, reduce wear and maintain correct alignment during the open/close cycle.
How to Install MK Gate Valves:
The installation of MK valves must be carried out by expert personnel to ensure maximum efficiency and safety. The main stages include:
- Flow preparation: Ensure that the piping system is completely isolated and that there is no residual pressure.
- Valve placement: The valve must be positioned so that the direction of flow is correctly aligned with the indication on the valve body.
- Connection: Valves are generally connected via threads or flanges (according to ASME B16.34).
- Leak Test: Once installed, the valve should be tested for fluid leaks.
Sectors of Use:
The MK Gate 1/2 inch and Globe 1/2 inch are mainly used in the following sectors:
- Industrial and manufacturing sector: For the regulation of gases and liquids in industrial plants.
- Energy sector: In gas and oil management, especially in oil and gas pipeline applications.
- Chemical sector: In the management of fluids in chemical environments, where good resistance to corrosion is required.
- HVAC Industry: For flow control in heating and cooling systems.
Maintenance of MK Valves:
To ensure optimal operation over time, it is important to carry out regular maintenance on the gate and globe valves. This includes:
- Periodic lubrication of moving parts, such as the disc and lead screw.
- Check the sealing of the gaskets and replace if necessary.
- Check the structure for corrosion or damage due to high pressures and temperatures.
Safety Regulations:
MK valves are designed to comply with all industrial safety regulations. While some valves may not be CE compliant, it is important to ensure that they comply with local and international safety regulations (such as ASME B16.34). In case of use in environments where the valve is not CE compliant, it is recommended to update the machine according to current regulations.
Why Buy a Used MK Valve:
Purchasing a MK gate valve , in particular the Gate 1/2 inch and Globe 1/2 inch , is an advantageous solution for those looking for a reliable product at a competitive price. If well maintained, these valves can provide years of service without compromising performance. Buying used allows you to save significantly on purchase costs without sacrificing quality.
Conclusion:
MK gate valves in Gate and Globe models are robust and precise solutions for controlling the flow of liquids and gases in various industrial plants. Thanks to their build quality, reliability and long life, these valves are an excellent choice for companies that need reliable components for their daily operations. Buying a used vehicle in good condition allows you to get maximum value without compromising performance.
