ZUVELLO Double Check Quick Release Valve for Haldex 289714 — 2-Pack Steel, 1/4 in Supply 3/8 in Delivery

ZUVELLO 289714 double check quick release valve (2-pack) is a direct-fit replacement for Haldex systems that speeds air evacuation to restore brake responsiveness.

This pair of quick release valves is engineered to match common OEM numbers and restore fast air discharge for heavy-duty braking systems. Machined from corrosion-resistant steel and matched to the original port sizes, these valves are built to drop into place with minimal fuss. They help maintain proper pneumatic brake behavior by releasing trapped air quickly when pressure is reduced, and come packaged as two identical valves to service dual-circuit or redundant locations.

How does this valve fit into my vehicle's air brake system?

The ZUVELLO 289714 functions as a double check quick release valve that monitors two air sources and releases air rapidly when pressure drops. It installs at the delivery port location and interfaces with standard 1/4" supply and 3/8" delivery tubing. The valve coordinates with Haldex-style systems and matches multiple OEM part numbers for a straightforward replacement.

• Supply port: 1/4"; delivery port: 3/8" for common hose sizes.
• Crack pressure: approximately 1 PSI for quick actuation.
• Direct-fit to Haldex-compatible mounting points and connections.
• Two valves included to service both circuits or a twin installation.

What performance and durability can I expect from these valves?

Manufactured from durable, rust-resistant steel, these valves resist corrosion and wear common in road environments. Their construction helps preserve consistent air flow and rapid release over time, reducing the need for frequent replacements. While designed for hard use, routine inspection and correct installation ensure long life.

• Steel body treated to resist corrosion and surface wear.
• Engineered for reliable air release cycles in heavy-duty applications.
• Sold as a matched pair to maintain balanced braking performance.

How easy is installation and which part numbers does it replace?

Installation is intended to be quick and simple: disconnect the old valve, transfer fittings, and fit the ZUVELLO unit in its place. No special tools are usually required beyond common pneumatic and hand tools. These valves are offered as direct replacements for a wide range of OEM references to simplify parts matching.

• Direct replacement for 289714 and compatible OEM numbers (see list below).
• Installation typically completes in minutes for a trained technician.
• Comes as a 2-pack so both sides or multiple locations can be serviced at once.

• Replaces part numbers such as: 289714, A12-14980, 25175160, 1676745C, WKN32041, 289714N, 289714X, 289714RX, 1676745C1, 20QE2288, KN32041, 034012, 34012.

What should I check after fitting these quick release valves?

After installation, verify there are no air leaks and that the brake system rebuilds pressure correctly. Confirm the quick release action by cycling the brakes and observing that pressure drops clear the delivery lines quickly. Regular inspections of fittings and ports help maintain performance.

• Pressure-test the circuit to ensure no leaks at supply and delivery ports.
• Cycle brakes to confirm fast, complete air release at crack pressure (~1 PSI).
• Inspect fittings and seals for proper seating and torque.

Who is this for: The ZUVELLO 289714 double check quick release valve 2-pack is aimed at fleet mechanics, heavy-truck service shops, and owner-operators who need a reliable, OEM-fit replacement for Haldex-compatible air brake systems. It's appropriate for anyone maintaining air-powered braking on trailers or heavy-duty trucks who wants a corrosion-resistant, ready-to-install spare that matches common OEM part numbers.
