Key Features
| Feature | Description |
|---|---|
| Exact OEM Fit | Machined to match original equipment geometry and bolt‑pattern for direct drop‑in replacement. |
| High‑Strength Construction | Constructed from robust alloy or stainless materials to withstand pressure cycling and fluid abrasion. |
| Optimised Sealing Surface | Precision‑finished valve plate face ensures consistent seal engagement and reduces leakage or pressure loss. |
| Maintenance‑Friendly Design | Simplified replacement layout allows fast service with minimal tooling and machine downtime. |
Installation & Usage Tips
- Stop the machine, relieve residual fluid pressure and secure all system components before servicing.
- Remove the existing valve plate, clean the mating surfaces thoroughly of contaminants, old gasket material or buildup.
- Install the 15H178 Plate Valve aligning bolt holes properly and using correct torque settings as per manufacturer guidelines.
- Ensure the sealing face mates flush against its counterpart and that no foreign particles interfere with the interface.
- After reinstalling, cycle the system at low pressure and check for proper valve switching and no leaks before returning to full service.
- During routine maintenance, inspect the valve plate for signs of wear, pitting, or corrosion – prompt replacement preserves system performance.
???? Frequently Asked Questions
It functions as the valve‑plate interface inside a pump or spray system, controlling fluid flow paths and sealing against high pressure to maintain system integrity.
Installation is straightforward if standard disassembly procedures are followed—clean surfaces, align properly, torque bolts to spec, and perform a low‑pressure test before full operation.
Replace the valve plate if you observe signs of fluid leakage at the interface, decreased system output, excessive noise or visible wear on the sealing surface to maintain optimal performance.
