Our electric actuated carbon steel wafer butterfly valves offer a powerful and cost-effective solution for automated control in general industrial, utility, and process applications where strength and reliability are critical.
Equipped with advanced electric actuators, these valves provide precise on/off or modulating control. They integrate seamlessly into automated systems, ensuring accurate and repeatable valve positioning for reliable process management and shutdown protocols.
Electric actuation eliminates the need for pneumatic infrastructure like compressors and air lines. This reduces upfront capital investment, simplifies installation, and lowers long-term energy consumption and maintenance costs compared to air-operated systems.
Designed for modern plant control, our electric actuators communicate directly with PLC, DCS, and SCADA systems. They provide essential feedback on valve status, enabling centralized monitoring, remote operation, and enhanced process data logging for improved operational oversight.
Our electric carbon steel wafer butterfly valves deliver exceptional performance and value in a wide range of industrial, municipal, and commercial systems.
In power plants, controlling cooling water is crucial. Our electric large diameter butterfly valve provides reliable isolation for main condenser lines and auxiliary cooling circuits, ensuring plant efficiency and safety.
For utility lines like process water and compressed air in paper mills, a robust PN16 butterfly valve is essential. The carbon steel body offers required strength, while electric actuation integrates into the mill's control system.
In district energy systems, managing hot and chilled water distribution requires dependable automation. An electric 6 wafer butterfly valve provides precise control for zone isolation, optimizing energy delivery across the network.
To handle mildly abrasive slurries and process water, our epoxy coated butterfly valves provide an extra layer of protection. The durable coating on the carbon steel body enhances resistance to external corrosion and internal wear.
Every plant relies on utility systems. A carbon steel butterfly valve is the ideal, cost-effective choice for automated control of plant-wide systems, including cooling tower water, compressed air, and general process water lines.
In non-critical utility applications within oil and gas facilities, like firewater or cooling water, a reliable WCB butterfly valve offers a strong, pressure-containing boundary that meets industry standards for general service.
For large municipal networks, our electric butterfly valve for water line applications provides reliable shut-off in pumping stations and mains. Remote SCADA operation enables efficient management of the entire water grid.
In commercial fire sprinkler systems, a butterfly valve DN100 PN16 with an electric supervisory switch is critical. It provides reliable isolation while signaling its status to the fire alarm control panel, ensuring system readiness.
Our butterfly valve JIS 10K is designed to meet flange standards in shipbuilding, ensuring a perfect fit-up and reliable performance for onboard utility systems like fresh water, sanitation, and HVAC.
This document details a procurement project for a leading Mexican EPC firm, focusing on the challenges of sourcing reliable, cost-effective actuated valves for a critical utility infrastructure project and the quantifiable results achieved through partnership with JRVAL.
Client: A prominent Engineering, Procurement, and Construction (EPC) firm based in Monterrey, Mexico.
Project: Construction of a new water treatment and distribution facility for a major industrial park, requiring 110 units of electrically actuated wafer butterfly valves.
Product Focus: Electric Carbon Steel Wafer Butterfly Valve (ASTM A216 WCB Body, EPDM Seat, SS410 Stem), Sizes DN100 to DN500 (4" to 20").
As an EPC contractor, the client faced intense pressure to deliver the project on schedule and within a tight budget, while guaranteeing long-term operational reliability to the end-user. Their procurement team identified three primary risks:
1. Budgetary Constraints: Initial quotes from established North American and European brands exceeded the allocated valve budget by approximately 30-35%, threatening project profitability.
2. Supply Chain & Quality Risks: Past experiences with other international suppliers highlighted risks of inconsistent quality, including incomplete material traceability records (MTRs) and dimensional deviations that required costly on-site modifications.
3. Actuator Integration Complexity: The project specification required the use of the EPC's preferred electric actuator brand for system-wide standardization. This necessitated sourcing bare-stem valves with a universally compatible top-flange, a feature not always prioritized by fully integrated valve-actuator suppliers.
JRVAL was selected based on our ability to address these challenges with a transparent, vertically-integrated manufacturing approach and verifiable engineering compliance.
Our operation, based in an 81,426 m² facility with 11 core CNC machining centers, begins at our in-house foundry. This allows direct control over the chemical composition of the ASTM A216 WCB casting, ensuring it meets the upper range of the standard's specifications for durability. This model eliminates intermediary markups, enabling us to provide a final quote that was 24% below the average from established Western brands, directly optimizing the client's procurement costs.
We provided a comprehensive documentation package for pre-shipment approval. Each valve was supplied with: 1) Material Test Reports (MTRs) to EN 10204 3.1 for the body and stem. 2) In-house hydrostatic test certificates confirming Zero Leakage (Rate A) performance per ISO 5208, tested bi-directionally at 1.1 times the rated pressure. 3) Final QC dimensional inspection reports using calibrated instruments. We also formally welcomed a client-appointed third-party inspector (e.g., BV, SGS) to witness final testing at our facility at their discretion.
A critical success factor was the precise machining of the valve's top works. All valves were manufactured with a standardized ISO 5211 mounting flange and a double-D stem drive. This guaranteed a perfect, direct-mount fit for the client's specified electric actuators, eliminating the need for costly custom brackets and significantly reducing on-site installation time for the mechanical and electrical teams.
Our direct control over the casting and machining schedule enabled a firm delivery commitment. The entire 110-valve order was manufactured and shipped within 12 weeks, compared to the 18-20 week lead times quoted by other suppliers. This 6-week reduction in lead time provided the EPC with a valuable buffer in their master construction schedule.
The partnership delivered measurable improvements against the project's key performance indicators (KPIs):
- Capital Cost Reduction: The procurement of the valve package came in \$52,000 under the original budget, directly enhancing the project's overall profit margin.
- Quality Assurance: Zero Non-Conformance Reports (NCRs) were issued during the client's incoming goods inspection. 100% of the valves met the specified material, testing, and dimensional requirements.
- Operational Reliability: Now 20 months into operation, the facility reports zero failures or leaks from the installed JRVAL valves. The client is covered by our standard 24-month warranty for free spare parts, and our use of industry-standard seat dimensions ensures low-cost, readily available replacements for future maintenance cycles.
Our commitment to quality is verified by internationally recognized standards. We provide the documentation to prove it.
