Wafer valves are a popular choice due to their compact design and lower cost. They are held in place by the compression of two pipeline flanges. JRVAL offers specialized wafer bodies for enhanced performance.
The ultimate wafer valve for demanding applications requiring superior corrosion resistance and an enhanced safety margin against pressure and system stress.
Engineered for high-stress industrial systems, this valve features an extra-thick body for superior resistance to pipeline pressure and mechanical stress, ensuring long-term reliability.
A testament to JRVAL's manufacturing prowess, the Signet body combines robust performance with unparalleled aesthetic and functional details for premier installations.
A revolutionary design for applications demanding minimal downtime. This valve allows for rapid in-line seat replacement without special tools.
Lug-style valves feature threaded inserts (lugs) that allow them to be installed into a system using bolts. This design is ideal for dead-end service or applications where one side of the piping may need to be disconnected for maintenance.
The premium choice for lugged connections, combining the versatility of dead-end service with maximum corrosion resistance and guaranteed dimensional accuracy.
The workhorse for industrial dead-end service. This valve provides the strength of carbon steel and the installation flexibility of a full lug design at a competitive price point.
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 valve connection. It is the preferred choice for larger sizes, higher pressures, and critical applications.
The pinnacle of reliability for flanged connections, engineered for critical service in corrosive environments where a leak-proof seal and structural integrity are non-negotiable.
Delivers the same robust, leak-proof performance for demanding industrial applications where high-grade corrosion resistance is not the primary requirement.
The valve body is only part of the solution. Selecting the correct actuator is critical for performance, safety, and efficiency. This guide compares the most 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. |
