High-Density Casting for Lug Butterfly Valve

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.

Learn More About Our Process

THE SOURCE MANUFACTURER

We control the entire manufacturing process, from raw CF8/CF8M stainless steel investment casting to electropolishing and final assembly. This guarantees superior corrosion resistance, purity, and performance in every valve.

PREMIUM RAW MATERIALS

We use only certified CF8/CF8M/CF3M stainless steel from trusted suppliers, verified by in-house PMI testing to ensure alloy integrity for maximum corrosion resistance and durability.

SANITARY & PRECISION MACHINING

Our CNC centers achieve ultra-smooth, crevice-free surfaces (Ra ≤ 0.4μm) and electropolishing, critical for preventing contamination and ensuring easy CIP/SIP in hygienic applications.

PROVEN LEAK-PROOF DESIGN

Our optimized seat design and precision-machined disc/stem interface guarantee bubble-tight, zero-leakage performance, validated by rigorous pressure and cycle testing for long-term reliability.

Wholesale Stainless Steel Butterfly Valve

Key Application Industries

The following are the representative application industries of this valve. Since our stainless steel wafer butterfly valves are highly versatile, many specific industries are not listed individually but are fully supported.

Oil & Gas Industry

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.

Power Generation

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.

Municipal Water Supply

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.

Shipbuilding Industry

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.

Environmental Protection Industry

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.

Food Processing Industry

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.

Mining & Metallurgical Industry

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%.

Refrigeration & Cold Storage Industry

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.

Seawater Desalination

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.

Engineered for Demanding Environments

Our stainless steel valves are built to perform under the toughest conditions. From highly corrosive media to cryogenic temperatures and sanitary applications, we provide certified solutions that ensure purity and reliability.

Corrosive Environments

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.

Particle Wear Environment

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.

Prone to Oscillating Environments

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.

Space-Constrained Environment

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.

Cryogenic Environment

JRVAL cf8m and hastelloy c276 valves pass Charpy V-notch impact tests per GOST 9454-78, ensuring toughness at cryogenic temperatures.

Water Supply & Sewage Treatment systems

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.

Semiconductor Ultrapure Water System

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).

HVAC System

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).

Gas System

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.

CASE STUDY: PURETASTE BEVERAGES

How JRVAL’s sanitary stainless steel valves eliminated contamination risks and improved CIP efficiency for a leading beverage producer.

The Challenge

Hidden Contamination Hotspots

PureTaste Beverages was struggling with inconsistent batch quality. Their existing valves had internal crevices and rough surface finishes that trapped residual product, fostering bacterial growth and making Clean-in-Place (CIP) cycles ineffective.

Production Inefficiency

To combat the contamination, they were forced to perform lengthy, manual teardowns and cleaning, leading to excessive downtime, high labor costs, and wasted cleaning agents. Product purity was constantly at risk.

The JRVAL Solution & Result

Engineered for Purity

JRVAL supplied our sanitary stainless steel wafer valves, featuring an electropolished, crevice-free internal surface (Ra ≤ 0.4μm) and a void-free seat design. This ultra-smooth finish provides no purchase for microbial growth and allows for complete drainage.

Restored Quality and Efficiency

The impact was transformative. Contamination issues were eliminated, ensuring consistent product quality and safety. The plant’s CIP cycles became highly effective, drastically reducing cleaning time and resource consumption, which directly improved their operational bottom line.

"The difference was night and day. JRVAL's sanitary valves solved a problem we'd been fighting for years. Our cleaning is faster, and our product quality is more reliable than ever. It was the right investment."
