Our butterfly valve stainless bodies are produced from a high-density casting process. This ensures a solid, non-porous structure, completely free from sand holes and other casting defects. The result is superior strength and maximum durability.
Learn More About Our ProcessWe specialize in manufacturing actuator-ready butterfly valves. Our process integrates robust material science with high-precision machining to deliver valves that form the reliable core of any automated flow control system.
Founded by casting experts, we guarantee material integrity from the source. Through PMI spectral testing, we verify alloy compositions, ensuring every butterfly valve casting strictly adheres to ASTM/EN standards for optimal performance and longevity in automated systems.
Our advanced CNC centers machine critical interfaces, like the ISO 5211 mounting pad, to exacting tolerances. This precision guarantees effortless, accurate alignment with any standard electric or pneumatic actuator, ensuring reliable automated control.
With two decades of field validation in automated applications, our valve designs are proven to be sound and reliable. This experience means our products deliver consistent, dependable performance when integrated into complex control systems.
Our bare shaft butterfly valves are the trusted choice for automated systems where reliability and precise control are non-negotiable. Explore some of their key applications.
In automated dosing and transfer systems, the passivated stainless steel body and resilient EPDM seat provide reliable service for a wide range of chemicals. The actuator-ready design of our Wafer Type Butterfly Valve ensures immediate integration into PLC-controlled processes.
For automated filter backwash, aeration control, and chemical feed lines, our valves provide bubble-tight shutoff. The high-rebound EPDM Seat Butterfly Valve resists abrasion and common water treatment chemicals, ensuring long-term reliability in municipal plants.
The acid-passivated, crevice-free surface of our SS Butterfly Valve is ideal for hygienic applications. When automated, they provide precise control over WFI (Water for Injection) loops and Clean-in-Place (CIP) systems, meeting strict industry standards.
Integrated into Building Management Systems (BMS), our valves automate chilled and hot water loops for efficient climate control. A 6 Inch Butterfly Valve is a common choice for main lines, offering superior flow characteristics compared to traditional globe valves.
Our valves, trusted by system integrators, are perfect for automated liquid food processing lines. The food-grade EPDM seat withstands repeated high-temperature sterilization cycles, making us a preferred wafer butterfly valve supplier for this demanding industry.
In automated stock preparation and white water systems, our valves handle fibrous media reliably. The robust design of the Butterfly Valve SS316 with a replaceable seat ensures long service life and easy maintenance, minimizing costly plant shutdowns.
In automated ballast and bilge water systems, our valves provide dependable performance in corrosive saltwater environments. The compact design of the Marine Butterfly Valve saves critical space and weight, essential for shipboard installations.
Our valves are integral to automated cooling water intake and circulation systems in power plants. A large-diameter 8 Inch Butterfly Valve provides high-capacity flow control with minimal pressure drop, enhancing overall plant efficiency and safety.
For automated slurry transport and dewatering circuits, our valves are built to withstand abrasion. The field-replaceable seat makes the butterfly valve for slurry application a cost-effective choice, allowing for quick renewal of the primary wear component.
How a mid-sized industrial water treatment OEM optimized costs and secured its project timeline by switching to JRVAL's actuator-ready butterfly valves.
Client: A leading system integrator in Southeast Asia specializing in containerized water purification skids for industrial applications.
Project: A large-scale deployment of 80 purification skids for a new textile manufacturing facility, requiring over 500 units of DN80 to DN300 stainless steel butterfly valves.
Mr. Faisal, the Head of Procurement, faced a critical sourcing challenge. Their trusted European valve supplier quoted a 12-week lead time, jeopardizing the project deadline. Meanwhile, low-cost alternatives from unverified suppliers presented significant risks of material non-conformance and dimensional inaccuracies on the critical actuator mounting interface, which would be catastrophic for their standardized assembly line.
Mr. Faisal's team initiated a technical due diligence process with JRVAL. Instead of marketing claims, our engagement focused on verifiable data and process transparency.
We submitted a complete technical documentation package for review, including:
- Material Test Reports (MTRs) for the specified SS316 (ASTM A351 CF8M) heat lot, confirming Nickel content at 10.2% (Standard requires 9.0-12.0%), ensuring robust corrosion resistance.
- In-house PMI verification report. We were transparent that project-specific third-party witnessing (e.g., by SGS, BV) was available at the client's arrangement and cost—a standard and respected industry practice.
- Pressure Test Certification confirming each valve was tested to 1.1 times its rated pressure (16 bar valves tested at 17.6 bar) with zero leakage according to API 598 Rate A standards.
The core of the client's challenge was actuator integration. We provided:
- Dimensional QC Reports for the first articles, showing the ISO 5211 mounting pad and stem drive dimensions were machined to a tolerance of +/- 0.1mm. This guaranteed flawless mounting of their locally sourced pneumatic actuators, eliminating the need for on-site rework.
- The bare stem configuration provided them the flexibility to select actuators based on their specific control requirements and local availability, optimizing both cost and functionality for their skid design.
Leveraging our position as a source manufacturer, we offered a level of control unattainable from trading companies.
- Our production plan was built around our in-house foundry and 11 CNC centers within our 81,426 m² facility. This vertical integration allowed us to commit to a firm delivery schedule.
- The total order was fulfilled in 5 weeks, a 58% reduction compared to the 12-week lead time from the European supplier, effectively mitigating the project's primary schedule risk.
The partnership delivered tangible, measurable outcomes that directly impacted the project's bottom line.
Our commitment to quality is verified by internationally recognized standards. We provide the documentation to prove it.
Ready to configure for your automation project?
Absolutely. Our "actuator-ready" design features a top flange and stem drive machined to the ISO 5211 standard. This guarantees seamless, direct mounting of any compliant pneumatic, electric, or hydraulic actuator, eliminating the need for custom brackets and ensuring full interchangeability for our OEM clients.
We provide comprehensive quality assurance. Every batch is supported by a Material Test Report (MTR) verifying the chemical composition. For our ASTM A351 CF8M (SS316), we ensure Nickel content is at the high end of the standard (≥10%) for superior corrosion resistance. Full traceability is maintained from our in-house foundry to the finished product.
Our design prioritizes longevity. The valve body wall thickness meets the demanding HG/T chemical industry standard, providing enhanced resistance to pressure and pipeline stress. This, combined with our superior material composition and passivated finish, results in a valve built for extended service life in demanding industrial environments.
Yes, our valves are engineered for modular maintenance. The seat is designed for easy field replacement without specialized tools. The key benefit is a drastically lower Total Cost of Ownership (TCO), as you can service the valve's primary wear component in minutes, minimizing downtime and avoiding the cost of replacing the entire valve body.
Our "zero leakage" commitment refers to achieving API 598 Rate A bubble-tight shutoff in both directions. This is accomplished through a combination of a precision-machined, spherically profiled disc edge and a high-resilience EPDM seat with superior elasticity retention, ensuring a reliable, long-lasting seal.
