Valve Brass Isol Screwdriver Cxc 22X22mm

The 22mm Brass Screwdriver Isolation Valve (CxC) is a heavy-duty in-line shut-off valve designed for high-flow hot and cold water systems. Unlike a standard lever-handle ball valve, this model features a "Screwdriver Slot" (slotted spindle) that sits flush with the brass body, making it ideal for installations where space is limited or where a tamper-resistant design is required.

Technical Specifications

• Size: 22mm x 22mm (Standard South African copper/poly-pipe sizing).
• Connection: Compression x Compression (CxC) (Includes brass nuts and olives).
• Material: High-grade DZR (Dezincification Resistant) Brass.
• Mechanism: Quarter-turn ball valve with a slotted screwdriver spindle.
• Pressure Rating: Suitable for high-pressure systems up to 1,600 kPa (16 Bar).
• Compatibility: Fits 22mm Hard/Half-hard Copper and Class 10/12 HDPE or PEX piping.

Key Performance Features

• Tamper-Resistant Design: Because there is no protruding handle, the valve cannot be accidentally knocked open or closed. This makes it perfect for public areas, schools, or industrial sculleries in the Heidelberg - GP region.
• Space-Saving Profile: The compact, flush spindle allows the valve to be installed in tight ceiling voids, under-floor manifolds, or inside narrow plumbing ducts where a traditional lever handle would not have room to turn.
• DZR Brass Durability: Engineered to resist the corrosive effects of mineral-heavy water. The DZR construction ensures the internal ball doesn't seize, which is vital for the Winter Bulk 2026 maintenance cycle.
• High Flow Rate (L/min): The 22mm "Full Bore" design ensures there is no significant pressure drop, making it suitable for main feed lines to geysers or multi-fixture bathrooms.
• Instant Isolation: A simple quarter-turn with a Kaufmann screwdriver provides a positive shut-off, allowing for rapid repairs without draining the entire building's water system.

Installation & Professional Tips

• Sanding the Pipe: Before fitting the valve, use a piece of emery cloth to clean the ends of the 22mm copper pipe. A clean surface ensures the brass olive creates a perfectly watertight seal.
• No Tape Required: Compression fittings rely on the mechanical deformation of the brass olive. You do not need PTFE Tape on the threads; however, a small smear of Belatori Plumbers Hemp paste on the olive can help it "seat" better on older pipes.
• Tightening Protocol: Slide the nut and olive onto the pipe, insert the pipe into the valve body, and tighten the nut by hand. Use a Kaufmann shifting spanner to tighten the nut approximately one to one-and-a-quarter turns. Over-tightening can "crush" the olive and cause a leak.
• Directional Check: While most ball valves are bi-directional, it is best practice to install the valve so the screwdriver slot is easily accessible for future maintenance during the Easter 2026 period.
• Operating the Valve: To close the valve, turn the slotted spindle 90°. When the slot is parallel to the pipe, the valve is Open. When the slot is perpendicular (across) the pipe, the valve is Closed.

Common Use Cases

• Geyser Isolation: Installed on the 22mm cold water feed to a high-pressure geyser.
• Main Line Branching: Isolating a specific wing of a building or a large industrial wash-bay.
• Pump Manifolds: Serving as a shut-off point before or after a Pascali Pump for easy filter cleaning.
• Public Restrooms: Providing a hidden shut-off for basin or urinal ranges to prevent vandalism.

Pro Tip: If the valve has been in the "Open" position for a long time, it may become slightly stiff. Use a wide-head Kaufmann screwdriver that fits the slot perfectly to avoid "burring" the brass edges when you apply the initial torque to close it.
