Your expert guide to selecting the perfect worm gear operated butterfly valve. Effortlessly manage large pipelines and high-pressure systems with the precision and reliability of JRVAL's vertically integrated manufacturing.
Add critical layers of safety and monitoring to your manual valves. JRVAL offers factory-installed options for enhanced operational security and regulatory compliance.
Wafer valves are held in place by pipeline flanges, offering a compact and economical solution. JRVAL elevates this design with heavy-body construction and innovative quick-change seat technology for unmatched performance.
The ultimate wafer valve for demanding applications, featuring a high-density, zero-porosity casting and an enhanced safety margin for superior corrosion and pressure resistance.
Engineered for high-stress industrial systems, this valve's extra-thick body offers superior resistance to pipeline pressure and mechanical stress, ensuring long-term reliability.
A premium concentric valve engineered for exceptional performance and aesthetics. The Signet Series combines robust materials with meticulous craftsmanship for demanding industrial applications.
A revolutionary design for applications demanding minimal downtime. This valve allows for rapid, in-line seat replacement, drastically reducing maintenance costs.
Lug-style valves feature threaded inserts, allowing them to be bolted to one flange for dead-end service. This design is crucial for applications where downstream piping may be disconnected for maintenance under upstream pressure.
The premium choice for lugged connections, combining dead-end service versatility with maximum corrosion resistance and guaranteed dimensional accuracy from a zero-porosity casting.
The industrial workhorse for dead-end service. This valve provides the strength of carbon steel and installation flexibility with deep-cast markings for full traceability.
A highly reliable and economical option, providing excellent strength and durability for a wide range of industrial and municipal applications.
Featuring two integral flanges that mate directly with pipeline flanges, this design provides the most secure and rigid connection. It is the preferred choice for larger sizes, higher pressures, and critical applications.
The pinnacle of reliability for flanged connections, engineered from zero-porosity castings for critical service in corrosive environments where a leak-proof seal is non-negotiable.
Delivers robust, leak-proof performance for demanding industrial applications where high-grade corrosion resistance is not the primary requirement.
Engineered for the most demanding services, these valves feature offset disc and shaft geometry to minimize seat wear and operating torque, providing superior sealing and longer life in critical applications.
The high-performance workhorse for demanding industrial processes. Its double-offset design lifts the disc off the seat upon opening, drastically reducing wear and extending the valve's service life.
Engineered for critical applications where fire safety is non-negotiable. This valve provides reliable shutoff and is designed to maintain its integrity under extreme fire conditions, meeting stringent API 609 fire-safe standards.
The apex of valve technology for zero-leakage performance. The triple-offset, friction-free design ensures absolute shutoff in high-pressure, high-temperature, and cryogenic services.
The valve body is only part of the solution. Selecting the correct actuator is critical for performance, safety, and efficiency. This guide compares common options for butterfly valves.
| Actuator Type | Operating Principle | Key Advantages | Best Applications / Industries |
|---|---|---|---|
| Handle (Lever) | Manual quarter-turn (90°) operation. Often includes a locking mechanism or notched plate for positioning. |
|
|
| Gear (Worm Gear) | A manual handwheel turns a gearbox, which multiplies torque to make opening/closing large valves easier. |
|
|
| Pneumatic | Uses compressed air to move a piston or diaphragm, which rotates the valve stem. Can be spring-return or double-acting. |
|
|
| Electric | An electric motor drives a gear train to rotate the valve stem. Can offer sophisticated control options. |
