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 pair our robust stainless steel wafer butterfly valves with advanced electric actuators, delivering precise, repeatable, and easily integrated solutions for modern industrial automation and remote control systems where reliability is paramount.
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 electric stainless steel wafer butterfly valves are the trusted choice for applications demanding precise control, data integration, and unwavering reliability.
In modern smart buildings, our electric hvac butterfly valve integrates seamlessly with Building Management Systems (BMS) for precise control of chilled and hot water loops, enhancing energy efficiency and occupant comfort.
For automated filter backwashing and chemical dosing in water purification plants, our reliable water butterfly valve provides precise, repeatable control that can be remotely operated and monitored via SCADA systems.
The compact design of our wafer type butterfly valve is ideal for equipment manufacturers. Its simple power requirements and control signals make it easy to integrate into packaged pumping systems, filtration units, and process skids.
On automated factory floors for controlling process water, compressed air, and utility lines, a dependable industrial butterfly valve with electric actuation provides a cost-effective and low-maintenance solution for plant-wide automation.
For ballast water systems, engine room cooling circuits, and onboard utilities, a stainless steel marine butterfly valve with an IP68-rated electric actuator ensures reliable performance and corrosion resistance in harsh maritime environments.
In large-scale agricultural or golf course irrigation, a 6 inch stainless steel butterfly valve allows for automated zone control, enabling precise watering schedules programmed via a central controller to conserve water and optimize growth.
For modulating the flow in industrial ovens, dryers, and heat exchangers, a high temperature butterfly valve with a specialized seat and a high-temp electric actuator provides stable and accurate temperature regulation.
In corrosive bleaching and chemical recovery areas, a fully lined butterfly valve with electric actuation offers superior protection. The non-reactive liner prevents chemical attack, ensuring long service life and process purity.

How a Building Management Systems (BMS) integrator mitigated project risks and improved installation efficiency by partnering with JRVAL for a time-sensitive HVAC upgrade.
Application: Automated flow control for chilled and hot water circuits in a 50,000 m² commercial office building retrofit.
Requirement: A package of 250+ electric actuated stainless steel wafer butterfly valves (DN80 to DN300), requiring seamless integration with a BACnet-based BMS, adherence to a strict budget, and a guaranteed delivery schedule.
The BMS integrator faced a multi-faceted procurement challenge that put the project's profitability and timeline at risk:
1. Budgetary Pressure & Lead Time Conflicts: Quotes from Tier-1 European valve brands, while technically compliant, exceeded the allocated valve budget by 18-25%. Furthermore, their projected lead times of 14-16 weeks threatened to delay the critical commissioning phase of the project.
2. Integration Complexity: Sourcing valves and electric actuators from separate suppliers would require significant on-site labor for assembly, wiring, and function testing. This introduced risks of compatibility issues and increased the potential for installation errors and delays.
3. Long-Term Reliability Concerns: The end-client specified a minimum 10-year service life for all core components. The integrator needed verifiable assurance of material quality and manufacturing consistency to back their own performance guarantees and avoid costly post-installation service calls.
JRVAL was selected based on our ability to provide a comprehensive, factory-direct solution that addressed the client's technical, commercial, and logistical requirements with quantifiable data.
We supplied each valve as a fully assembled and tested unit, complete with a modulating electric actuator (4-20mA control). This factory-assembled approach eliminated on-site assembly, reducing the integrator's on-site electrical labor for this scope by an estimated 20%. Each actuator was pre-calibrated, ensuring it could be connected directly to the BMS control panels, simplifying the commissioning process.
As a foundry with 81,426 m² of manufacturing space, we control the entire production process. The valve bodies and discs were cast in-house from certified CF8M (SS316) raw materials. This vertical integration provided two key advantages: First, it guaranteed material traceability, supported by our standard EN 10204 3.1 material certificates. Second, it allowed us to control the production schedule directly, mitigating the supply chain risks associated with third-party foundries.
Our solution was underpinned by a transparent quality assurance framework. Each valve was hydrostatically tested to 1.5 times its PN16 pressure rating, achieving bi-directional zero-leakage performance as defined by API 598 Rate A. The valve bodies were manufactured to the HG/T 3037 standard, ensuring a wall thickness that provides superior structural integrity and corrosion allowance compared to lighter-duty alternatives. A full quality dossier, including QC dimensional reports from calibrated instruments, was provided for the client's records.
By leveraging our in-house production capabilities with 11 key CNC machining centers, we committed to and met a 9-week delivery schedule, a 40% reduction compared to the average lead time from distributors. This enabled the client to begin installation ahead of schedule. The total cost of the JRVAL package resulted in a 22% saving against the average quote from Tier-1 brands, bringing the valve procurement well within the project's budget.
The strategic shift to JRVAL's foundry-direct model delivered measurable success:
- Budget Adherence: Achieved a 22% cost reduction on the valve package, contributing significantly to the project's overall profitability.
- Schedule Acceleration: Reduced valve delivery lead time from a potential 16 weeks to a firm 9 weeks, de-risking the project timeline.
- Zero Failures: 100% of the 250+ valve assemblies have operated without leaks or actuator failures in the first 24 months of continuous operation.
- Service & Support Framework: The project is backed by our standard 24-month warranty covering free spare part replacement. Post-warranty, the standardized components ensure straightforward sourcing for long-term maintenance.
Our commitment to quality is verified by internationally recognized standards. We provide the documentation to prove it.
