I AM SELLING KSB 3G6K6K MANUAL BUTTERFLY VALVES PRESSURE 16 BAR DN 150 TEMPERATURE 80 DEGREES 

Technical Data Sheet: KSB 3G6K6K/PN16 DN 150 Manual Butterfly Valve

General Description

The KSB butterfly valve model 3G6K6K/PN16 is a manual valve used to control fluid flow in various industrial sectors. With a nominal diameter (DN) of 150 mm, it is designed to operate in systems with a maximum pressure of 16 bar and an operating temperature of up to 80°C. This type of valve is ideal for applications requiring high pressure resistance and operational reliability.

Components and Materials

• Body : Usually made of cast iron or steel, the valve body provides strength and durability while protecting the internal parts.
• Disc : The disc, also made of steel or coated cast iron, is the moving element that regulates the flow of fluid. It is operated manually via a lever or handwheel.
• Seals : The seals are made of elastomer or PTFE, materials chosen to guarantee hermetic sealing and resistance to chemical agents.
• Stem : Made of stainless steel, the stem connects the disc to the external drive system and ensures the rotation of the disc.

Technical Specifications

• Working Pressure : PN16 (16 bar)
• Nominal Diameter (DN) : 150 mm
• Operating Temperature : Up to 80°C
• Connection : Flanged, suitable for safe and stable mounting in piping systems.
• Operation : Manual, with lever or handwheel for direct control.

Application Sectors

The KSB 3G6K6K valve is used in various sectors such as:

• Water Treatment : For flow control in wastewater treatment plants.
• Chemical Industry : Where materials resistant to corrosive fluids are required.
• HVAC systems : For the management of air flows or heating/cooling fluids.
• Energy : Used in cooling circuits and steam distribution.

Maintenance and Control of Used Vehicles

To ensure long life and optimal operation, it is essential to carry out regular checks on:

• Seals : Check the integrity of the seals to prevent leaks.
• Disc and Stem : Make sure the disc moves freely and the stem is free of corrosion.
• Body : Visually inspect the body for any signs of wear or damage.

When purchasing a used valve, it is important to check that there are no signs of corrosion, that the seals are in good condition, and that the valve has been properly maintained.

Advantages of Buying Used

Purchasing a used KSB valve can be advantageous due to its lower cost compared to a new one and its robust construction, which ensures a long service life even after prolonged use. However, it is essential to carefully check the condition of the valve to ensure it is still functional and efficient.

Formulas for Optimal Use

To determine the pressure drop across the valve, the following formula can be used:

$\Delta$

Where:

• ΔP\Delta P $\Delta$ $P$ is the pressure drop.
• KK $K$ is the valve leakage coefficient (provided by the manufacturer).
• ρ\rho $\rho$ is the density of the fluid.
• VV $V$ is the velocity of the fluid.

This type of calculation is useful for correctly sizing the valve in a specific system, ensuring optimal operation without overloads.

Conclusions

KSB butterfly valves, model 3G6K6K/PN16 DN 150, are reliable and robust solutions for fluid control in a variety of industrial applications. Finding them used in good condition represents an opportunity to save money without compromising operational quality and reliability
