Specifications and Procedures:
The document discusses the selection and operation of pressure control valves, focusing on the adjustment range and material selection based on operational requirements. It highlights that standard adjustment ranges can be exceeded in special cases with lower valve utilization and reduced precision requirements. For example, a pressure reducer with a range of 0.8-2.5 bar can operate satisfactorily at 0.5 bar.
Material Selection:
Materials should be chosen according to operational demands and resistance tables. For toxic or flammable fluids, a closed spring bonnet with a leakage connection may be necessary to safely discharge fluids in case of a control part defect.
Examples and Calculations:
The document provides several examples of selecting appropriate valves based on calculated Kv values, which are adjusted by 30% to determine the minimum Kvs value required. It includes examples for different media such as methanol, water, CO2, and steam, detailing the selection of specific valve types and their characteristics.
Flow and Pressure Calculations:
It explains the calculation of Kv values for both undercritical and overcritical pressure differentials, using formulas for flow coefficients, volumetric flow rates, and pressure differences. The document also covers the determination of nominal diameters to minimize pressure losses and operational noise, recommending specific flow velocities for different pressure ranges.
Valve Selection Guidelines:
Guidelines for selecting valves include ensuring the desired setpoint is near the upper limit of the adjustment range and choosing materials suitable for the application. The document emphasizes the importance of understanding operational behavior to use valves outside catalog-specified application areas in special cases.
Conclusion:
The document concludes with a focus on the know-how of pressure reducing valves, which reduce high, often fluctuating pressures to an adjustable, constant level.

Overview: The document provides detailed technical specifications and guidelines for selecting and operating pressure reducing valves (Druckminderventile) manufactured by MANKENBERG GmbH. It covers various aspects such as valve selection, installation, operation, and maintenance, with a focus on ensuring optimal performance and safety.
Valve Selection:
- Type and Size: Choose a valve with a Kvs value at least 30% greater than the calculated Kv value for the maximum flow rate and minimum differential pressure. Consider additional factors for high-viscosity or vaporizing liquids.
- Pressure and Material: The nominal pressure stage should exceed the maximum system pressure without safety margins. Consider temperature effects as per DIN standards.
- Adjustment Range: Select an adjustment range where the desired back pressure is at the upper limit for better control accuracy.
- Elastomers: Choose based on operating temperature and medium requirements. Gases under high pressure can diffuse into elastomers, causing damage upon decompression.
Flow Velocity Recommendations:
- Liquids: 1 - 5 m/s
- Saturated Steam: 10 - 40 m/s
- Superheated Steam: 15 - 60 m/s
- Gases up to 2 bar: 2 - 10 m/s
- Gases over 2 bar: 5 - 40 m/s
Installation and Operation:
- Control Line: Plan for a control line if the valve is designed for it, ensuring it is connected at least 10 times the nominal width behind the valve.
- System Protection: Install a safety valve to prevent exceeding the maximum operating pressure. Use dirt traps or filters to protect the valve from solid particles.
- Sealing and Isolation: Pressure reducers are not required to be completely leak-proof. For increased seat tightness, special cone seals and larger control surfaces can be used.
- Bypass and Isolation: Plan shut-off devices before and after the valve for maintenance and system closure. A bypass may be necessary for emergency operation.
Special Considerations for Steam:
- Ensure the membrane is filled with water before operation to prevent overheating.
- Do not insulate the valve to avoid overheating and damage to elastomers.
- Use a steam dryer to remove water quickly and prevent damage from wet steam.
Maintenance: Regular cleaning and maintenance are essential. Ensure oil, grease, and silicone-free devices when ordering spare parts.

Description
Float valves automatically regulate liquid levels in closed or open (non-pressurized) containers without auxiliary energy. A float detects the liquid level and directly controls the valve via a lever. A change in level immediately alters the flow rate. NV 16e is a pipeline valve for horizontal or vertical flow, with a soft-sealing cone. The valves are equipped with a float rod on which a float with an inner tube is mounted (Mantel float SR 8). The liquid level can be continuously adjusted by moving the float on the float rod.
