For valves installed in high pipe racks or confined spaces, pneumatic actuation eliminates the need for manual access. Our China wafer butterfly valve offers a compact, lightweight solution for easy installation and remote operation.
Designed for durability, the pneumatic actuator and valve assembly withstand frequent opening and closing cycles without performance degradation. As a dedicated wafer butterfly valve manufacturer, we ensure long-term reliability for batching processes.
Pneumatic actuation is inherently spark-free, making it the safe choice for explosive or flammable atmospheres (ATEX zones). This makes our industrial butterfly valve suitable for chemical plants, refineries, and mining sites.
In processes requiring multiple valves to operate in a coordinated sequence, pneumatic control provides the rapid and precise response needed for perfect timing. A reliable concentric butterfly valve supplier ensures consistent performance across all units.
While the carbon steel body provides robust, economical strength, our ability to customize internal disc and seat materials ensures reliable automated performance in a wide range of corrosive services.
For applications involving chlorinated or treated water, standard EPDM can degrade. We specify a Hypalon seat butterfly valve for superior resistance to oxidation and chemical attack, ensuring long life in disinfection processes.
In chemical dosing and light processing, broad chemical resistance is essential. A PFA lined butterfly valve provides an inert barrier, protecting valve internals from a wide spectrum of corrosive chemicals and ensuring process purity.
To combat corrosion in coastal installations or on ships, our valves feature a Duplex steel or Ni-Al-Bronze disc with a thick epoxy coating. This makes it a durable marine butterfly valve built to withstand saltwater spray and high humidity.
Ozone is a powerful oxidizer that rapidly degrades common elastomers. For these advanced water treatment applications, a butterfly valve viton seat (FKM) is essential, providing excellent resistance to ozone and ensuring long-term sealing integrity.
When handling slurries containing both abrasive particles and corrosive chemicals, a tough, resilient lining is required. Our wholesale wafer butterfly valve can be configured with a thick rubber lining to resist both wear and chemical attack simultaneously.
Demineralized water is aggressive and can leach materials. As experienced China pneumatic butterfly valve suppliers, we recommend a polished SS316L disc with an EPDM or PTFE seat to prevent ionic contamination and maintain water purity.
Automating a Chemical Batching System for a Thai Specialty Chemicals Plant
Client: A mid-sized specialty chemical manufacturer in Thailand.
Project: Upgrading a manual chemical batching process to a fully automated system to improve product consistency and operational safety.
Product: 45 units of Pneumatic Actuated Carbon Steel Wafer Butterfly Valves (DN80-DN200), specified with WCB Body, SS316 Disc, and PTFE Seat for chemical compatibility.
The client's primary objective was to eliminate batch-to-batch inconsistencies caused by manual valve timing errors. However, their past experience with low-cost actuated valves was poor, marked by premature failures at the actuator-stem connection and seat leakage after only a few thousand cycles. Quotations from premium European brands were approximately 40% over the project's capital expenditure budget. The challenge was to find a manufacturing partner who could provide a reliable, high-cycle automation solution that was both technically robust and financially viable, avoiding the pitfalls of sourcing from typical trading companies.
JRVAL was selected based on our vertical integration as a foundry-direct manufacturer, which allowed us to provide verifiable quality control from raw material to final assembly. Our solution focused on addressing the client's specific technical pain points.
As a manufacturer with a 20-year casting heritage, we controlled the entire material lifecycle. We provided EN 10204 3.1 Material Test Certificates (MTCs) for each heat of the ASTM A216 WCB castings. Our internal standard ensures the chemical composition, particularly carbon and manganese levels, is maintained in the upper quartile of the ASTM standard, which enhances structural integrity and durability in high-cycle applications. This level of transparency gave the client's engineering team complete confidence in the valve body's material foundation.
Recognizing the client's previous failures, we focused on the mechanical interface. The valve stem's square drive and the pneumatic actuator's output shaft were CNC-machined to a tolerance of ±0.05mm. This precision fit minimizes mechanical play, significantly reducing shear stress and eliminating the primary failure mode of connection wear common in less precisely assembled units. Each assembled valve underwent a 50-cycle operational test at our facility before shipment.
Our integrated manufacturing model enabled us to provide the complete solution at a price point that resulted in a 28% cost saving compared to the initial European quotes, successfully bringing the project within budget. Leveraging our 81,426 m² facility and 11 key CNC centers, we managed a production lead time of 7 weeks for the full order, delivering 3 weeks ahead of the client's 10-week installation deadline.
Each of the 45 valves underwent a hydrostatic shell test at 1.5x PN16 and a bi-directional seat test at 1.1x PN16, achieving zero leakage which exceeds the requirements of API 598 Rate A. A complete documentation package, including MTCs, dimensional inspection reports from calibrated instruments, and individual pressure test certificates, was provided. We openly state that client-appointed third-party inspections (e.g., SGS, Bureau Veritas) are welcomed at our facility at the client's expense, demonstrating our confidence in our processes.
We supported our product with a 24-month warranty covering the entire valve and pneumatic actuator assembly. We guarantee free spare part replacement for any quality issues within this period. Our design adheres to international standards, ensuring that wear parts like seats and seals can be easily sourced from the market after the warranty period, thus optimizing the Total Cost of Ownership (TCO) from a maintenance perspective.
