Product Features & Advantages

Our positioning plate surpasses standard fixtures through superior engineering and material science.

Unmatched Durability & Material Excellence

Fabricated from high-grade, corrosion-resistant materials selected for specific industrial environments (e.g., offshore, chemical processing). The material undergoes stringent quality checks to ensure it meets the demands of heavy-duty applications.

Precision Engineering for Perfect Fit

Every Precision positioning plate is manufactured using advanced CNC machining. This guarantees dimensional accuracy, consistent hole patterns, and a flawless fit with your valve assembly, eliminating play and misalignment that can lead to wear or failure.

Enhanced Operational Stability

The design incorporates features that dampen vibration and distribute mechanical load evenly. This significantly enhances the valve's stability and operational responsiveness, preventing unintended movement.

Reduced Lifetime Costs

By ensuring valves remain correctly positioned, our plate minimizes seat wear, stem damage, and leakage. This translates to dramatically reduced maintenance frequency, lower spare parts costs, and less unplanned downtime, offering a superior return on investment.

How to Install the Positioning Plate

Installing Qifei's Valve parts positioning plate is a straightforward process designed for efficiency.

1. Preparation & Safety: Isolate the valve from the process line, depressurize, and follow all site-specific Lockout/Tagout (LOTO) procedures.
2. Alignment: Position the plate against the valve's mounting interface, ensuring all bolt holes align perfectly with the valve body and actuator brackets.
3. Securing: Insert high-tensile bolts through the aligned holes. Hand-tighten all nuts initially to ensure even seating.
4. Torquing: Using a calibrated torque wrench, tighten the bolts in a cross-pattern to the manufacturer's specified torque value. This prevents warping and ensures even pressure distribution.
5. Verification: Conduct a visual and operational check to confirm the valve moves freely through its full cycle without binding and that the plate is securely fixed.

FAQ

Is this positioning plate compatible with valves from different manufacturers?

Yes, while we offer standard models for common valve types, the key advantage of our product is its precision engineering. We can manufacture plates to match the exact specifications of virtually any industrial valve from major manufacturers. Providing the valve's flange or mounting dimension drawing is the best way to ensure compatibility.

What is the main difference between your plate and a standard washer or bracket?

Standard washers or generic brackets only provide basic spacing or support. Our positioning plate is a precision positioning plate engineered for dual purpose: it acts as a robust structural interface that accurately aligns multiple components (valve, actuator, piping) while resisting complex forces (shear, vibration, torsion). It is a performance-critical component, not just a simple spacer.

How does this component reduce maintenance needs?

By eliminating micro-movements and misalignment, the plate prevents asymmetric wear on valve stems, seats, and seals. It also ensures actuation forces are applied correctly, preventing binding and gear damage. This leads to longer intervals between overhauls and fewer emergency repairs.

Can you provide custom material certifications?

Absolutely. For critical applications, we provide full traceability and material certification (such as EN 10204 3.1) upon request, ensuring the material composition and mechanical properties meet your project's strict specifications.
