Actuator Type

Double Acting: Utilizes compressed air to power both the open and close strokes of the valve.

Single Acting / Spring-Return: Uses compressed air for one stroke and a mechanical spring for the return stroke, providing a fail-safe position.

- Normally Closed (NC) / Fail-Close: The spring closes the valve upon loss of air pressure.

- Normally Open (NO) / Fail-Open: The spring opens the valve upon loss of air pressure.

Control Type

On/Off (Discrete): For fully open or fully closed service, providing simple and reliable isolation.

Modulating (Throttling): For precise flow control by positioning the disc at any intermediate angle. Requires an electro-pneumatic positioner.

Special Configurations

Electro-magnetically Released: A specialized double-acting actuator designed for specific safety or emergency shutdown (ESD) applications.

Custom Solutions: Other actuator configurations and accessories are available upon request to meet unique application requirements.

High-Density Casting: Zero Porosity Guaranteed

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.

Sterilization Chemicals (CIP/SIP)

Clean-in-place and sterilize-in-place systems use aggressive chemicals and high temperatures. A teflon lined butterfly valve offers superior chemical inertness, ensuring valve integrity during repeated sanitation cycles.

OEM PARTNERSHIP CASE STUDY

How a mid-sized industrial water treatment OEM optimized costs and secured its project timeline by switching to JRVAL's actuator-ready butterfly valves.

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.

THE SOURCING DILEMMA: BALANCING COST, RISK, AND INTEGRATION

Mr. Tan, 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.

THE SOLUTION: A TRANSPARENT & DATA-DRIVEN PARTNERSHIP

Mr. Tan's team initiated a technical due diligence process with JRVAL. Instead of marketing claims, our engagement focused on verifiable data and process transparency.

Technical & Quality Verification Process

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 12% (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.

Precision for Seamless Automation (The "Bare Stem" Advantage)

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.

Supply Chain Reliability & Production Control

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.

QUANTIFIABLE RESULTS & KPIs

The partnership delivered tangible, measurable outcomes that directly impacted the project's bottom line.

Cost Optimization: Achieved an 18% reduction in the total valve procurement cost compared to the incumbent European brand's quote, directly improving the project's profit margin.
Schedule Adherence: Reduced valve delivery lead time from 12 weeks to 5 weeks, enabling on-time completion of the skid assembly and avoiding potential late-delivery penalties.
Quality Assurance: Zero non-conformances (NCRs) were reported during the client's incoming quality inspection and assembly process across all 500+ units.
Long-Term Value: The client benefits from our standard 2-year warranty with free spare part replacement. Post-warranty, the standardized modular seat design ensures maintenance parts can be easily sourced, contributing to a lower Total Cost of Ownership (TCO).

"JRVAL's transparency was the deciding factor. They didn't just give us a price; they provided the complete documentation package we needed for our due diligence. The cost savings were significant, but the real value was in their manufacturing control and reliable lead time. They became a predictable and vital part of our supply chain."

Mr. Tan Head of Procurement, Singapore-based EPC firm.

TECHNICAL & PROCUREMENT FAQ

What does "Universal Flange Compatibility" mean in practice for my project?

It means our Uni-Fit Series valve body is designed to self-center between multiple international flange standards, including JIS 5K/10K/16K, and KS. For procurement managers and engineers, this simplifies inventory, eliminates sourcing errors for global projects, and makes retrofitting existing, varied piping systems significantly faster and more reliable.

How do you guarantee the premium quality of your stainless steel?

As a source manufacturer with our own foundry, we control quality from day one. Every valve is supplied with a Material Test Report (MTR). Specifically for our ASTM A351 CF8 (SS304), we ensure the Nickel content is at the 9% maximum allowable standard, providing superior corrosion resistance and verifiable quality you can trust.

What are the tangible benefits of the "Rapid Installation" design?

The lightweight, compact wafer body directly translates to lower labor costs and reduced project time. It's easier and faster for a single technician to handle and mount, especially in tight spaces or during time-critical plant shutdowns. This design minimizes system downtime and accelerates project completion, directly impacting your bottom line.

Are these valves "actuator-ready" and what standard do they follow?

Yes, absolutely. Our bare stem valves are designed for seamless automation. They feature a standardized ISO 5211 mounting pad and stem drive. This guarantees direct, reliable integration with any compliant pneumatic or electric actuator, providing you with the flexibility to use your preferred actuator brand without needing custom brackets or modifications.

What is your warranty policy and how are spare parts handled?

We stand behind our manufacturing with a comprehensive 2-year warranty, which includes free replacement of spare parts like seats or seals. Because our valves are built to international standards, sourcing maintenance parts is straightforward even after the warranty period, ensuring a low Total Cost of Ownership (TCO) for your assets.
