CASE STUDY: PNEUMATIC WAFER BUTTERFLY VALVE

Optimizing Automated Skids for a Malaysian Water Treatment Integrator

Project Scope: Supply of 350 units of DN80-DN200 pneumatic actuated SS316L wafer butterfly valves for their new series of automated water purification systems destined for industrial parks.

THE CHALLENGE: BALANCING PERFORMANCE, AUTOMATION & COST

Mr. Singh's team faced a critical procurement challenge. Their existing European mid-tier valve supplier provided reliable products but with two major drawbacks: high unit costs that eroded project profitability by 15-20%, and inconsistent lead times fluctuating between 8 to 12 weeks, which delayed skid assembly and final delivery. They required a partner who could provide automation-ready valves that met strict performance criteria without the prohibitive brand premium.

Their key evaluation criteria were:

Material Integrity: Verifiable SS316L (CF8M) composition for handling chlorinated water and mild chemical solutions.
Sealing Performance: Bi-directional zero-leakage sealing (compliant with API 598 Rate A) to prevent backflow and ensure dosing accuracy.
Automation Compatibility: Fast-acting, reliable pneumatic actuators that could integrate seamlessly with their Siemens PLC control systems.
Supply Chain Reliability: A firm, predictable lead time of under 6 weeks to align with their production schedule.
Cost Optimization: A target cost reduction of over 20% for the valve package to improve their market competitiveness.

OUR SOLUTION: ENGINEERING VALUE & SUPPLY CHAIN CERTAINTY

We engaged with Mr. Singh's engineering team in a detailed technical review, positioning ourselves not just as a supplier, but as a manufacturing partner. Our solution was built on verifiable data and transparent processes.

Quantified Cost Optimization with Superior Material

We delivered a final per-unit cost that was 22% lower than their previous supplier. This was achieved not by compromising quality, but by leveraging our in-house casting capabilities. We provided MTRs for every heat lot, demonstrating that our CF8M castings consistently contain 10.5-11.5% Nickel and 2.2-2.5% Molybdenum, exceeding ASTM A351 minimums to offer enhanced corrosion resistance and a longer operational life.

Guaranteed Performance & Transparent Verification

Every valve underwent hydrostatic testing at 1.5x its rated pressure, certified to API 598 Rate A for zero leakage. To build trust, we fully facilitated their request to have a local, independent inspection agency perform PMI (Positive Material Identification) on a random 5% sample of the first batch at our factory before shipment, with all units passing verification.

Streamlined Automation & Reduced Maintenance

The pneumatic actuators, with a tested cycle time of under 1.5 seconds, met their precision control needs. Furthermore, we highlighted our modular, quick-change EPDM seat. Based on their operational parameters, we projected this feature could reduce their clients' potential maintenance downtime by over 80% over the valve's lifecycle, as only the seat needs replacement, not the entire unit.

Reliable Production & Delivery Schedule

Drawing on the capacity of our 81,426 m² facility and 11 dedicated CNC machining centers, we committed to and met a firm 5-week lead time for the entire 350-unit order. This predictability allowed Mr. Singh's team to optimize their assembly line scheduling, eliminating previous bottlenecks caused by supplier delays.

Comprehensive After-Sales Support

We provided a 24-month warranty covering free replacement of non-wearing parts. As all our valve components are manufactured to international standards (e.g., ISO 5211 for actuator mounting), we assured the client that even post-warranty, sourcing compatible spare parts from the open market would be straightforward, guaranteeing a low Total Cost of Ownership (TCO).

The material traceability and consistent dimensional accuracy from JRVAL gave us the confidence to switch suppliers. Their pneumatic valves have performed reliably in the field for over 18 months. The primary benefit for us was achieving significant cost optimization without compromising the performance integrity of our dosing systems.

PNEUMATIC ACTUATED BUTTERFLY VALVE FAQ

How is the pneumatic actuator sized for your high-performance valve?

Our actuators are precisely sized with a minimum 30% safety torque factor over the valve's requirements. This ensures sufficient power to overcome dynamic flow forces and the high sealing compression of our high-resilience EPDM seat, guaranteeing reliable, bubble-tight shutoff (API 598 Rate A) throughout the valve's extended service life.

What fail-safe options are available for critical applications?

We offer both Double-Acting (fail-in-place) and Spring-Return (fail-safe) actuators. The spring-return models can be configured as "Fail-Close" or "Fail-Open" upon loss of air pressure, providing essential process safety. The robust spring packs are designed for high-cycle life, matching the durability of the valve itself.

How does the actuator's construction match the valve's superior metallurgy?

Our standard actuator features a hard-anodized aluminum body for excellent environmental resistance. For applications requiring our Duplex/Super Duplex valves, we can supply actuators with specialized protective coating systems qualified to ISO 12944 C5-M, mirroring the valve body's protection and creating a fully corrosion-resistant automated package.

Can this valve be integrated into our PLC/DCS control system?

Yes. The actuator is designed for seamless automation. It features a standard NAMUR interface for mounting solenoid valves and a VDI/VDE 3845 top mount for accessories like limit switch boxes (position feedback) and electro-pneumatic positioners (for precise throttling), ensuring full compatibility with modern industrial control systems.

How does automation affect maintenance compared to a manual valve?

Automation simplifies maintenance. The actuator is a self-contained, lubricated-for-life unit. Crucially, it pairs with our Modular Maintenance valve design. The seat can be replaced in minutes without disturbing the actuator or control wiring, reducing downtime by up to 80% and significantly lowering the total cost of ownership for the automated assembly.
