Application Case Study

Enhancing Automation Reliability for a Malaysian Palm Oil Refinery's Utility System

Project: Upgrading the plant's steam and cooling water circulation system with reliable, automated valves for integration into their new Distributed Control System (DCS).
Product: 68 units of Electric Actuated Carbon Steel Wafer Butterfly Valves (DN100-DN300), specified with WCB Body, SS316 Disc, and EPDM Seat.

The Challenge: Mitigating Operational Risks in a High-Humidity Environment

The client's existing motorized valves were failing prematurely. The primary issues were actuator motor burnout due to moisture ingress in the high-humidity environment and mechanical failure at the stem-actuator interface caused by poor machining tolerances. This led to unreliable process control and frequent, costly manual interventions. Their project goals were twofold: source a robust, IP-rated electric valve solution and achieve this within a CAPEX that was approximately 25% lower than quotes from established European brands, without sacrificing long-term reliability.

The Solution: A Partnership Focused on Manufacturing Integrity & Engineering Detail

JRVAL was engaged as a manufacturing partner, not just a supplier. Our solution directly addressed the client's technical and financial requirements by leveraging our integrated production capabilities.

Foundry-Direct Material Control & Traceability

As a manufacturer with a 20-year casting heritage, we controlled the material at its source. We provided Material Test Certificates for each heat of the ASTM A216 WCB body castings. Our internal standard ensures the chemical composition, particularly carbon and manganese levels, is maintained in the upper quartile of the ASTM range. This enhances structural integrity and provides a superior foundation for the valve, a critical factor for long-term performance under thermal cycling in steam lines.

Precision-Engineered Interface for Electric Actuation

To prevent the client's previous mechanical failures, we focused on the valve-actuator interface. The ISO 5211 mounting flange and the stem's square drive were CNC-machined to a tolerance of ±0.05mm. This precise fit minimizes mechanical backlash and ensures efficient torque transmission from the electric motor, which is critical for accurate modulating control and preventing wear-related failures in automated systems. Each assembly's dimensional report was included in the documentation package.

Robust Actuator Selection & Environmental Protection

We supplied the valves with IP67-rated electric actuators, featuring die-cast aluminum housings with an anti-corrosion powder coating. This specification directly mitigated the risk of moisture ingress that caused the previous failures. The actuators included a manual override handwheel for emergency operations and internal torque limit switches to protect the motor and valve drivetrain from over-torque events.

Quantifiable Cost Optimization & Project Timeline Adherence

Our direct-from-foundry model enabled significant cost optimization. The final project cost was 22% lower than the client's initial quotes from European suppliers, bringing the project comfortably within budget. Leveraging our 81,426 m² facility and 11 CNC centers, we managed a production lead time of 6 weeks for the full order, delivering 2 weeks ahead of the client's critical maintenance shutdown schedule.

Transparent & Verifiable Quality Assurance

Each of the 68 valves underwent hydrostatic shell testing at 24 bar (1.5x PN16) and bi-directional seat testing at 17.6 bar (1.1x PN16), achieving bubble-tight shutoff (zero leakage) as per API 598 Rate A. We state clearly that client-appointed third-party inspections (e.g., SGS, Bureau Veritas) are welcomed at our facility at the client's expense, demonstrating full confidence in our processes.

Comprehensive Warranty and Long-Term Support

We backed our solution with a 24-month warranty covering the entire valve and electric actuator assembly, including free replacement of spare parts for any quality-related issues. Since our valves are built to standard dimensions, sourcing wear parts like seats and seals from the local market post-warranty is straightforward, contributing to a lower Total Cost of Ownership (TCO).

"We were specifically concerned about the actuator-to-valve connection, as that's where our previous units failed. JRVAL's focus on the ISO 5211 flange machining tolerance was evident in the QC reports they provided. After 18 months in a very humid environment, the valves are performing flawlessly with our DCS. The reliability has been excellent, and the initial cost savings were substantial."

Technical FAQ: Electric Actuated Carbon Steel Butterfly Valves

How do you ensure the reliability and longevity of the electric actuator?

Our electric actuated valves are engineered as a complete system to withstand demanding industrial environments. Reliability is ensured through:

  • Robust Environmental Protection: Standard actuators are IP67-rated with durable, powder-coated aluminum housings to prevent moisture and dust ingress, a common cause of electrical failure.
  • Precision Mechanical Interface: The ISO 5211 mounting flange and valve stem are CNC-machined to a tolerance of ±0.05mm. This precise fit eliminates mechanical backlash, ensuring efficient torque transfer and preventing premature wear.
  • Built-in Drivetrain Protection: All actuators include internal torque switches to prevent damage from over-torque events and thermal overload protection for the motor, safeguarding your investment.

What specifications do you need to select the correct electric actuator for my system?

To guarantee precise performance and integration, our engineers require the following details to select the optimal actuator:

  • Power Supply: The available voltage and phase (e.g., 220V AC 1-Phase, 380V AC 3-Phase, 24V DC).
  • Control Type: On-Off (fully open/closed) or Modulating (proportional control, typically via a 4-20mA or 0-10V DC signal).
  • Valve Operating Conditions: We will calculate the required torque based on the valve size, line pressure, and media type you provide.
  • Operating Environment: Any special conditions such as high ambient temperature or corrosive atmospheres that may require upgraded actuator specifications.

How do you guarantee the quality of your ASTM A216 WCB carbon steel body?

As a foundry-direct manufacturer with 20 years of casting expertise, we offer unparalleled material control:

  • Superior Metallurgy: Our WCB castings are held to the upper quartile of the ASTM standard's chemical composition, enhancing strength and providing a thicker, more durable valve body per HG/T standards.
  • Full Traceability: Every valve is supplied with an EN 10204 3.1 Material Test Certificate (MTC), providing a complete chemical and mechanical properties report for your quality records.
  • In-House Verification: We confidently welcome client-appointed third-party inspectors (e.g., SGS, BV) at our facility at the client's expense for complete verification.

What does "zero leakage" mean for your soft-seated butterfly valves?

Our "zero leakage" claim for EPDM or NBR seated valves is defined by the industry's most stringent standards. Each valve is tested to achieve bubble-tight shutoff under the following conditions:

  • Standard Compliance: The test procedure and acceptance criteria adhere to API 598 Rate A and ISO 5208 Rate A.
  • Bi-Directional Sealing: We guarantee this level of sealing performance in both flow directions, a result of our innovative seat design and precision-machined disc edge.
  • 100% Factory Testing: Every single valve undergoes this pressure test before shipment, and the results are documented in its final quality report.

What is your warranty policy and post-warranty support?

We stand behind our manufacturing quality with a comprehensive 24-month warranty covering defects in materials and workmanship for the complete valve and electric actuator assembly. For long-term value:

  • Free Spare Parts: During the warranty period, any necessary replacement parts are provided free of charge.
  • Low TCO: Our valves are built to international standards, meaning wear parts like seats and O-rings are easily sourced from local suppliers post-warranty, minimizing your total cost of ownership.
  • Lifetime Support: Our technical team is available online for prompt troubleshooting assistance throughout the life of the valve.
