SS High Performance Wafer Butterfly Valve - Without Actuator

Oil & Petrochemical Industry

The high performance double offset butterfly valve demonstrates excellent corrosion resistance in sulfur-containing crude oil and acidic water environments, with PTFE seats capable of withstanding media up to 200°C. In a petrochemical plant’s catalytic cracking unit, these valves have operated stably in sulfur-containing wastewater treatment for over five years without significant corrosion.

Power Generation Industry

The double offset butterfly valves feature a precision dual eccentric design, enabling rapid low-friction contact/separation between the disc and soft seat during operation. This minimizes wear and extends service life, making them ideal for large-diameter, high-cycle water systems in power plants.

Municipal Water Supply Industry

The double offset butterfly valve combines corrosion-resistant stainless steel with food-grade soft seals, preventing secondary contamination of potable water. This ensures safe and hygienic drinking water delivery in municipal water systems.

Marine/Shipbuilding Industry

SS316L exhibits a Pitting Resistance Equivalent Number (PREN) in seawater significantly higher than ordinary stainless steels; Duplex stainless steels, with a PREN value >35, are even more suitable for harsh marine environments. Our hpbv has obtained certifications from classification societies such as CCS, ABS, DNV, and LR.

Environmental Protection Industry

The high performance butterfly valves provide long-term reliable bubble-tight shutoff, effectively preventing hazardous gas/liquid leaks to meet strict environmental emission standards.

Food Processing Industry

The butterfly valve double offset employs a precision dual eccentric structure, minimizing physical damage to food materials (e.g., fruit pulp beverages, cream, sauces) by reducing friction during operation.

Metallurgical Industry

The China double offset butterfly valve is specifically designed for slurry applications with bidirectional sealing capability. It maintains tight closure under pressure fluctuations (forward: 25 bar/2.5 MPa, reverse: 10 bar/1.0 MPa).

Refrigeration Industry

JRVAL, as one of high performance butterfly valve manufacturers supply a comprehensive range from DN40 to DN5000+, covering all refrigeration system requirements. Material selection can be customized based on refrigerant type and operating conditions.

Seawater Desalination Industry

This sector demands valves capable of handling highly corrosive, high-chloride environments. For such applications, JRVAL, as one of double eccentric butterfly valve suppliers china, provides solutions featuring construction from materials like SS316L and Duplex stainless steel (PREN > 35 for superior pitting resistance) for exceptional durability.

High-Temperature & High-Pressure Environments

For demanding high-temperature, high-pressure environments, the answer to what is double eccentric butterfly valve lies in its performance: utilizing high-strength materials like 17-4PH for the stem (>900MPa tensile strength) to guarantee no deformation or fracture. The valve body materials are also certified and traceable to match the specific medium temperature.

Corrosive Environments

Even in highly corrosive media, JRVAL helps you understand what is a double offset butterfly valve by delivering API 598 Class VI / ISO 5208 Rate A bubble-tight zero leakage, achieved through precision machining and carefully selected premium sealing materials.

Abrasive Particle Environments

In Abrasive Particle Environments, while the broader double eccentric vs triple eccentric butterfly valve discussion often centers on sealing for critical services, JRVAL’s dual-offset design offers an inherent advantage: its closing mechanism allows the disc to progressively contact the seat, reducing particle embedding, and its quick-release opening lowers jamming risk by approximately 50% compared to concentric types.

Vibration Environments

In Vibration Environments, JRVAL employs precision pin-key or spline connections. This construction ensures the double offset valve disc and stem remain securely fastened without wobbling under high-frequency vibrations, guaranteeing precise actuation and operational integrity.

Space-Constrained Environments

Compared to traditional gate or globe valves, the JRVAL's double offset wafer butterfly valve provides exceptional space savings, reducing the required axial installation footprint by up to 80-90%, making it ideal for compact designs.

Low-Temperature Environments

As a premier double eccentric butterfly valve china supplier, JRVAL’s design for cryogenic applications features an optimized extended bonnet. This element keeps the packing gland and actuator away from the low-temperature media, preventing hardening or freezing to ensure reliable operation and sealing, with the packing area temperature maintained above 0°C.

Water Supply Systems

In the ongoing concentric vs eccentric butterfly valve comparison for water supply systems, JRVAL’s dual-offset design proves superior by reducing operating torque by 20-30%. This makes manual operation of large-diameter valves easier and allows for smaller, more economical actuators.

Wastewater Treatment Systems

In wastewater treatment, the double eccentric butterfly valve meaning is truly demonstrated by its practical performance: an anti-clogging internal cavity design minimizes dead zones to prevent sludge accumulation, while a reinforced stem sealing system protects against external leakage and corrosion from sewage.

Semiconductor Ultrapure Water Systems

For semiconductor ultra-pure water systems, the JRVAL's double eccentric butterfly valve guarantees purity. Its crevice-free design, combined with high-grade materials like polished CF8M and PTFE seats, prevents particle generation and contamination to maintain absolute system integrity.

Fire Protection Systems

A critical strength of the high performance butterfly valves is its rapid response in emergencies. When paired with a quick-acting actuator, the JRVAL emergency shut-off butterfly valve achieves closing times of just 1-5 seconds, depending on the valve size and actuator type, ensuring swift, reliable isolation.

HVAC Systems

When evaluating a high performance butterfly valve vs butterfly valve for HVAC systems, JRVAL’s hpbv excels with a Cv value 30-50% higher than equivalent seat valves. This superior flow capacity significantly reduces pump head loss and delivers remarkable energy savings.

Gas Systems

As detailed in our double offset butterfly valve catalogue, JRVAL strictly implements a robust anti-static design for gas systems. This ensures the electrical resistance between the stem-body and stem-disc is ≤10 Ohms, a safety margin far exceeding the industry standard of 1 kΩ for preventing static discharge.
