Gate valve FERRO ZGZ02 3/4" cast iron through-flow

FERRO ZGZ02 3/4" cast iron through-flow gate valve is designed for on/off control of liquid flow in plumbing and heating systems. The valve features a straight-through passage and a manual handwheel for simple operation. Constructed primarily from cast iron, the valve is intended for installations that require a reliable shut-off device for domestic and light commercial water and heating circuits.

Advantages

The cast iron body provides mechanical strength and dimensional stability under typical residential and light commercial use. The through-flow design minimises pressure drop when the valve is fully open, while the gate mechanism ensures a clear shut-off position. Manual operation gives direct tactile feedback during closing and opening, and the valve's simple design supports straightforward maintenance and long service life when used within its intended parameters.

Suitable for

• Domestic cold and hot water supply lines
• Residential heating circuits and radiator branches
• Light commercial plumbing where a manual shut-off is required
• Applications requiring a straight-through passage and low flow resistance when open

Key specifications

• Nominal size: 3/4"
• Body material: cast iron
• Flow type: through-flow (straight-through passage)
• Operation: manual handwheel
• Function: on/off shut-off gate valve
• Typical media: water for plumbing and heating systems

How to use

Install the valve in-line with the pipework so the flow follows the straight passage through the body; ensure correct thread sealing at connections according to pipe material and sealing method. Operate the valve by turning the handwheel: rotate clockwise to close and counterclockwise to open until the handwheel reaches the mechanical stop. For safe operation, depressurise and drain the section of the system before removing or servicing the valve. Follow local plumbing codes and standard installation practices for mounting and support to avoid stress on the valve body and connections.

Usage recommendations

Use the valve within typical domestic and light commercial temperature and pressure ranges for water-based systems. Avoid rapid cycling under high differential pressure and do not use the valve for throttling purposes; it is intended for full open or full closed positions. Regular visual inspection and occasional operation of the handwheel will help prevent seizing and prolong service life.
