Brass Shut-off Valve FERRO KOR4Z 3/4" (korek mosiężny)

Brass shut-off valve FERRO KOR4Z 3/4" is a compact inline manual valve made from brass for reliable control of flow in plumbing systems. Designed for use with water and other non-aggressive fluids, this valve provides a simple means to stop or allow flow in residential and light commercial installations. Its nominal 3/4" connection fits common pipe sizes used in heating, water supply and maintenance tasks where a durable, easy-to-operate shut-off is required.

Advantages

The brass construction ensures corrosion resistance and long service life in normal potable water and heating system conditions. The compact inline design enables straightforward installation in tight spaces and reduces pressure loss when fully open. Manual operation is intuitive and provides immediate shut-off without electrical power or complex controls. The valve's finish and sealing components are selected to deliver leak-tight performance under standard system pressures.

Suitable for

• Domestic water supply lines
• Heating system branch shut-off
• Maintenance and repair tasks requiring isolation of a pipe section
• Installations with non-aggressive fluids compatible with brass

Key specifications

• Material: brass body and fittings
• Connection size: nominal 3/4"
• Design: compact inline manual shut-off valve
• Applicable media: water and non-aggressive fluids
• Operation: manual on/off control

How to use

Isolate system pressure before installation or maintenance. Fit the valve into the pipeline using appropriate thread sealant or tape on the male threads as required by your piping system and tighten to recommended torque values for brass fittings. Operate the valve by turning the handle to the closed position to stop flow and to the open position to allow flow. Verify there are no leaks after installation by slowly re-pressurizing the line and inspecting threaded joints and sealing surfaces.

Usage recommendations

Use the valve in systems with fluids compatible with brass and avoid exposure to strongly corrosive or ammonia-containing media. For outdoor or aggressive-environment installations consider additional protective measures such as insulating or covering the valve. Regularly check for leaks and proper operation, especially after thermal cycling or long periods of inactivity.
