MK Gate Valves – 1/2 Inch Gate Model and 1/2 Inch Globe Model: Complete Technical Data Sheet

MK gate valves , 1/2-inch Gate and 1/2-inch Globe models, represent a high-quality choice for those seeking reliable and durable fluid control solutions in industrial plants. These models, known for their robustness and precision, are designed to ensure optimal performance, even under harsh operating conditions.

General Description of the Models:

MK gate valves are essential components in piping and plant systems where the flow of fluids and gases needs to be regulated, blocked, or diverted. Gate and globe , in particular, are ideal for precise flow control, with simple operation and a design that provides excellent pressure resistance.

Common Technical Features:

• Brand: MK
• Model: Gate 1/2 inch (shuttle valve), Globe 1/2 inch
• Size: 1/2 inch
• Reference standard: ASME B16.34 (for working pressure up to 1500 psi)
• Construction Material: Typically, these valves are made of stainless steel , carbon steel , or bronze alloys , depending on the application specifications. The materials chosen for MK gate valves are resistant to corrosion and wear, ensuring a long life.
• Valve Type: Gate and Globe.
• Operating Pressure: The working pressure of these valves varies, but generally they are well suited for low to high pressure systems (up to 1500 psi, according to ASME B16.34).
• Working Temperature: These models can operate in a wide temperature range, from -20°C to +200°C, but it is always advisable to check the detailed specifications based on the material.

Dimensions:

• Gate Valve 1/2 inch (shutter):
  • Main dimensions: 1/2 inch
  • Operating Pressure: Up to 1500 psi (per ASME B16.34)
  • Weight: Varies depending on the material (steel, bronze, stainless steel), but is generally around 0.5 - 1 kg.
• Globe Valve 1/2 inch:
  • Main dimensions: 1/2 inch
  • Operating Pressure: Up to 1500 psi (per ASME B16.34)
  • Weight: Usually lighter than the roller shutter, weighing 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 the flow of liquids and gases.

1. Gate Valve:

   • The MK Gate valve is used to completely open or close the flow of fluid in a piping system. Operation is simple: the disc (or wedge ) moves along the valve axis thanks to a crank or lever, allowing or blocking the flow of fluid. These valves are ideal for applications where complete closure is required.
   • Typical uses: hydraulic systems, oil and gas pipelines and in industrial fluid distribution systems.

2. Globe Valve:

   • The Globe MK valve is designed to precisely regulate fluid flow. The valve body has a distinctive shape that allows for greater adjustment than a gate valve, making it ideal for applications requiring fine flow regulation.
   • Typical uses: Heating, refrigeration, water treatment, and chemical applications.

Main Components of MK Valves:

• Valve Body: Constructed of steel, bronze, or stainless steel depending on the specific model, it offers strength and durability.
• Disc: The closing disc (for the Gate valve ) is designed to allow the flow to be hermetically sealed.
• Seals: High-quality seals made of durable materials such as graphite or PTFE, used to prevent leaks and ensure tightness.
• Bottom: The valve base is designed to provide stability, reduce wear, and maintain proper alignment during the open/close cycle.

How to Install MK Gate Valves:

MK valve installation must be performed by expert personnel to ensure maximum efficiency and safety. The main steps include:

1. Flow Preparation: Ensure that the piping system is completely isolated and that there is no residual pressure.
2. Valve Positioning: The valve must be positioned so that the direction of flow is correctly aligned with the indication on the valve body.
3. Connection: Valves are generally connected via threads or flanges (according to ASME B16.34).
4. Leak Test: Once installed, the valve must be tested to ensure there are no fluid leaks.

Areas of Use:

MK Gate 1/2 inch and Globe 1/2 inch valves are mainly used in the following industries:

• Industrial and manufacturing sector: For the regulation of gases and liquids in industrial plants.
• Energy Sector: In oil and gas management, especially in oil and gas pipeline applications.
• Chemical industry: In the management of fluids in chemical environments, where good corrosion resistance is required.
• HVAC Industry: For flow control in heating and cooling systems.

MK Valve Maintenance:

To ensure optimal operation over time, it is important to perform regular maintenance on gate and globe valves. This includes:

• Periodic lubrication of moving parts, such as the disc and lead screw.
• Check the seals for leaks and replace if necessary.
• Check the structure for corrosion or damage due to high pressure and temperatures.

Safety Regulations:

MK valves are designed to comply with all industrial safety regulations. While some valves may not be CE-approved, it is important to ensure they comply with local and international safety regulations (such as ASME B16.34). If used in environments where the valve is not CE-approved, it is recommended to upgrade the machine to comply with current regulations.

Why Buy a Used MK Valve:

Buying a MK gate valve , especially the 1/2-inch Gate and 1/2-inch Globe , is a great option for those looking for a reliable product at a competitive price. If properly maintained, these valves can provide years of service without compromising performance. Buying used allows you to save significantly on purchasing costs without sacrificing quality.

Conclusion:

MK -inch Gate and Globe valves are robust and precise solutions for controlling the flow of liquids and gases in various industrial systems. Thanks to their quality construction, reliability, and long life, these valves are an excellent choice for companies requiring reliable components for their daily operations. Buying a used valve in good condition allows you to get the most value without compromising performance.
