Choosing the correct valve body material is the first and most critical step. Stainless steel is the champion of corrosion resistance, but understanding its advantages against other common materials ensures optimal performance and cost-effectiveness.
| Feature | Stainless Steel (SS) | Carbon Steel (WCB) | Ductile Iron (DI) | Bronze / Copper Alloys |
|---|---|---|---|---|
| Corrosion Resistance | Excellent | Poor (requires coating) | Fair | Very Good (especially in marine) |
| Temperature Range | Very Wide (Cryogenic to High Temp) | Wide (but less than SS) | Limited | Moderate |
| Strength & Pressure | Very High | Highest | High | Moderate |
| Cost | High | Moderate | Low | Very High |
| Best Applications | Chemicals, Food & Beverage, Pharma, Marine, Corrosive Media | Oil & Gas, Steam, High-Pressure Industrial (non-corrosive) | Water, Wastewater, HVAC (general service) | Seawater, Desalination, Shipbuilding |
Engineered for dead-end service, our lug-style stainless steel valves combine superior material integrity with precision manufacturing. The threaded inserts allow for safe downstream maintenance without draining the entire system, making them indispensable in critical process lines.
The foundational valve, ready for your custom actuation. Ideal for OEM equipment manufacturers and system integrators who require the flexibility to mount their own specific brand or type of actuator.
For rapid, manual on/off control. The lever handle provides quick 90-degree actuation and clear visual position indication, perfect for smaller diameter lines requiring frequent, straightforward operation.
Provides mechanical advantage for easy and precise manual control of larger valves or high-pressure lines. The self-locking gearbox ensures the valve stays in position against flow-induced torque.
The choice for high-speed, high-cycle automation. Pneumatic actuators offer unparalleled reliability and speed, with spring-return options for fail-safe operation in critical chemical processing or safety systems.
For precise, remote automated control. Electric actuators integrate seamlessly with PLC and SCADA systems, offering modulating control for flow regulation and reliable operation where compressed air is not available.
With integral flanges for a secure, bolted connection, these valves offer maximum rigidity and sealing integrity. They are the premier choice for large-diameter, high-pressure pipelines in aggressive chemical, marine, and industrial environments.
The core flanged valve, precision-engineered and ready for custom actuator mounting. Its robust body provides a stable platform for any high-torque actuation system required by large-scale projects.
An uncommon but available option for smaller flanged valves where quick manual shutoff is needed. Provides a simple, direct-control solution for accessible pipelines.
The standard for manual flanged valves. The gearbox provides the necessary torque for effortless operation of high-pressure and large-diameter lines, ensuring precise and safe flow control.
Combines the ultimate sealing integrity of a flanged body with the precision of electric automation. Ideal for critical, large-scale process control and remote pipeline management.
Our stainless steel wafer valves offer compact, cost-effective, and versatile solutions. From robust, heavy-body designs for industrial use to modular, quick-change seats for hygienic applications, JRVAL provides the perfect wafer valve for your needs.
The ultimate industrial wafer valve. Its heavy-walled body exceeds standards, providing an enhanced safety margin and superior structural integrity for demanding applications. Available with bare stem, lever, gear, pneumatic, or electric actuators.
A revolutionary design for hygienic applications demanding minimal downtime. This valve's modular seat allows for rapid, in-line replacement, drastically reducing maintenance costs. Available with bare stem, lever, gear, or pneumatic actuators.
Engineered for the most severe services, these eccentric valves minimize seat wear and operating torque, providing superior, long-lasting sealing in critical applications from high-cycle throttling to zero-leakage isolation.
The high-performance workhorse. Its double-offset design lifts the disc off the seat, drastically reducing wear and extending service life in throttling and high-cycle services. Typically supplied with worm gear or automated actuators for precise control.
The apex of valve technology for zero-leakage performance. The friction-free, triple-offset design with a metal-to-metal seal ensures absolute, bubble-tight shutoff in high-pressure, high-temperature, and cryogenic services.
