The following are the representative application industries of this valve. Since butterfly valves can be applied to almost all industries (as long as the temperature and pressure are in line), many industries have not been listed.
SwiftSeat™ Wafer Butterfly Valve enable up to 70% faster on-site seat replacement, drastically cutting downtime and reducing maintenance costs by 30% with a 500,000-cycle seat life.
As one of leading stainless steel butterfly valves manufacturers, JRVAL offers valves in 304L, 316L, Duplex 2205, and Super Duplex 2507 stainless steels, meeting NACE MR0103/0175 to resist complex corrosion in power plants.
JRVAL hand lever operated butterfly valve undergo bubble-tight testing (API 598 Class VI), ensuring zero leakage and potentially saving a city water network over 5 million RMB annually in non-revenue water loss.
Our marine butterfly valve boast Lloyd’s Register, DNV, ABS, and CCS certifications, achieving an average MTBF over 25,000 hours for reliable shipboard operation.
For challenging applications like VOCs treatment, JRVAL, a wafer butterfly valve manufacturer, can supply specific coatings or Hastelloy options to meet stringent environmental demands.
JRVAL's sanitary butterfly valve feature FDA & (EC) 1935/2004 certified wetted parts and Ra ≤ 0.5μm surface polish, improving cleanability and reducing bacterial risk by over 30%.
JRVAL's ss butterfly valve feature reinforced stems and bushings with wear-resistant materials, reducing stem breakage risk by over 50% against high torque from slurries.
JRVAL's cryogenic butterfly valve offer ±1.5% flow control accuracy for cold storage brine/glycol systems, optimizing cooling efficiency by 5%, and achieve 2-4 second emergency shut-off in refrigerant lines, significantly reducing risk.
Leveraging 316L, Duplex, and Super Duplex stainless steel options, JRVAL corrosion-resistant butterfly valve excel in seawater desalination, effectively resisting highly corrosive brines and ensuring long-term operational reliability
JRVAL's PTFE lined butterfly valve with Hastelloy C-276 bodies deliver <0.02mm/year corrosion rate in wet chlorine gas – leveraging proprietary material database for cost-optimized solutions.
Replaceable-seat lever butterfly valves combat abrasive particles: Worn seats are field-replaced in minutes, extending service life by 200%+ and cutting maintenance costs 50-70% vs fixed-seat designs.
Lever operated butterfly valve with 17-4PH stem maintains API 609 sealing under vibration via dual eccentric design, produced in ISO9001 factory.
ISO 5752-compliant wafer valve (e.g. DN200 PN16 at 60mm face-to-face) save 70% axial space vs 230mm gate valves, certified to EN 558 Series 20 & API 609 Category A.
Cryogenic butterfly valve with SS304L/316L bodies eliminate brittle fracture (DBTT) at -20°C; L-grade carbon enhances weld integrity and cryogenic toughness.
Chinese-manufactured wafer style butterfly valve achieve EN 558 Series 20 ultra-short face dimensions for congested piping networks
Unlike fixed-seat alternatives that require full valve replacement upon damage, our design allows for rapid, cost-effective on-site seat replacement. For instance, in a wastewater treatment plant’s aeration tank, switching to JRVAL’s replaceable seat handle wafer butterfly valve reduced maintenance costs by 50-70% and cut maintenance time by over 60%, significantly enhancing operational efficiency and prolonging the valve’s lifespan.
Our HVAC butterfly valve offers superior performance with its efficient 90° quarter-turn operation. This design enables swift full open/close action and precise flow regulation, critical for rapid response and accurate control demands. Its low operating torque (30-50% reduction due to skeleton-free design) allows for easy manual operation via the lever butterfly valve, enhancing system efficiency and energy management.
In gas systems susceptible to seat wear or corrosion from contaminants like dust, condensate, or H₂S, our butterfly valve lever type provides a critical advantage through its replaceable seat design. This feature enables swift, on-site seat replacement, eliminating the need to replace the entire valve. For highly flammable and explosive environments, this significantly reduces hot work risks and minimizes system downtime, ensuring enhanced safety and operational economics.
Q: Is the “replaceable soft seat” easy to replace? Does it require special tools? |
A: Yes, replacement is straightforward. Our innovative replaceable soft seat design typically requires only loosening the wafer bolts, removing the valve from the pipeline (or performing online replacement depending on design), followed by easy extraction and installation of the seat. No specialized tools are needed – simply follow our replacement guide. |
Q: You mention the seat has “over 60% rubber content” – what advantages does this provide? How long will it resist aging? |
A: Higher rubber content (referring to the proportion of rubber matrix in the seat composite material) enhances elasticity and resilience, improving tolerance compensation between disc and seat for superior sealing. Combined with premium rubber compounds (e.g., high-grade EPDM, NBR, VITON®), this significantly improves aging resistance, chemical resistance, and temperature tolerance. Actual service life depends on operating conditions (media, temperature, pressure, cycling frequency, CIP parameters, etc.) |
Q:Can we install our own actuators on these “headless” valves? Are top connections standardized? |
A:Absolutely. Our stem tops and mounting platforms comply with ISO 5211 standards, enabling direct attachment of manual gear (levers/worm gears) or pneumatic/electric actuators from major brands. |
Q: What’s covered by your “material guarantee” – 304 or 316L stainless steel? |
A:We offer both 304 (CF8) and 316L (CF3M/CF8M) options based on application needs. Full material certification (MTC) per international standards is provided. |
Q: Can you manufacture valves with AS 2129 Table E or BS 4504 PN16 flanges? |
A:Yes. Our flange database covers global standards including AS 2129 (Tables D/E/F/H), AS 4087, and BS 4504 (PN6-PN40). Specify standard and pressure class when ordering. |
