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.
While heavy-body wafer type valves are typically designed for medium-low pressure applications, JRVAL’s butterfly valve incorporates GOST valve compliance through reinforced body wall thickness and thicker stems, which ensures enhanced safety margins and meets the rigorous strength requirements.
JRVAL can provide a special low-temperature epdm lined butterfly valve capable of withstanding -40°C or even lower, meeting the demands of extremely cold regions like Russia.
For municipal water supply, an integral body design offers greater robustness, while a split body facilitates maintenance on certain large-diameter valves. JRVAL, as a wholesale wafer butterfly valve provider, can supply either type based on specific needs.
Valve bodies are typically coated internally and externally with marine-grade heavy anti-corrosion coatings (usually ≥300μm thick). The stem and disc, often found in our butterfly valve ss316 models, are made from seawater-resistant materials.
For the environmental sector, valve bodies utilize heavy anti-corrosion coatings compliant with GOST standards (e.g., multi-layer epoxy or polyurethane, total thickness ≥300μm). The disc and stem of our ss butterfly valves are made from corrosion-resistant alloys to effectively resist erosion from environmental media.
In the food processing industry, the internal and external surfaces of our stainless steel butterfly valves are highly polished (Ra ≤ 0.8μm, even down to 0.4μm), feature a crevice-free design for easy CIP/SIP cleaning, and reduce bacterial growth risk. The seat fits tightly with the body, ensuring no media retention.
JRVAL as a leading wafer butterfly valve manufacturer offers “Mining Heavy-Duty” butterfly valves, featuring a thickened body (wall thickness increased by 20-30% over standard), reinforced stem and bushings, and an optimized seat fixation method. This design effectively resists high abrasion, high impact, and pipeline vibrations, extending the valve’s service life by over 30%.
JRVAL utilizes specially formulated low-temperature EPDM or PTFE seats, combined with an optimized stem sealing design. This ensures reliable sealing and operation of the center line butterfly valve in environments down to -50°C. Verified by low-temperature cycle testing, the leakage rate still meets Grade A after 50,000 cycles.
Our stainless steel wafer butterfly valve is constructed from premium materials such as CF8M, ensuring long-term performance against aggressive saline environments, complemented by robust seat options for reliable, bubble-tight sealing.
JRVAL offers teflon butterfly valve and viton lined butterfly valve using premium imported or domestic materials like PTFE and FKM. Precision molding and sintering processes ensure chemical stability and sealing performance. The teflon butterfly valve maintains A-grade sealing after 50,000 cycles in harsh acid/alkali environments.
JRVAL engineers tailor materials (body/disc/seat) and structural reinforcement for stainless steel wafer type butterfly valve based on particle characteristics (hardness, size, concentration), flow velocity, temperature, and vibration.
JRVAL centerline valve features thickened bodies, reinforced stems, and optimized disc-stem connections (multi-keyway or spline joints). This design enhances vibration resistance by 40% and withstands high-frequency shocks and particle impacts.
The JRVAL wafer style butterfly valve has a structural length strictly controlled to the EN 558 S20 international standard (compatible with GOST R 54808). Some models feature actuators that are 5-10% smaller than the industry average, making them suitable for narrow installation spaces.
JRVAL cf8m and hastelloy c276 valves pass Charpy V-notch impact tests per GOST 9454-78, ensuring toughness at cryogenic temperatures.
The JRVAL epdm coated butterfly valve is made of SS304L/SS316L stainless steel compliant with GOST 5632. It operates stably above 120°C and can withstand up to 140°C for short periods. Material traceability is ensured, and an EN 10204 3.1 certificate is provided.
Electropolished lug and wafer type butterfly valve with CF3M body and ptfe seat meets SEMI F81 standards for ultra-pure water systems (Ra≤0.38μm).
Our epdm butterfly valve is ideal for HVAC systems, offering resistance to hot water, ethylene glycol, and aging. It operates across -20°C to +130°C (-4°F to +266°F).
JRVAL's wafer butterfly valves have an anti-static design. Conductive materials connect the stem and body, dissipating static charges to the ground during operation. This prevents sparks and ensures compliance with safety standards like GOST 12.1.018-93.
