1. Manual Gearbox Operation for Effortless High-Torque Control
Engineered for easy operation, even in larger sizes or under high differential pressure.
High Mechanical Advantage: The multi-stage **worm gear operator (turbine head)** provides significant torque multiplication, making the opening and closing of the valve smooth and manageable with minimal operator effort, eliminating the need for large handwheels.
Durable & Reliable Gearing: The enclosed gearbox protects internal components from environmental contaminants, ensuring long-term reliability and consistent performance.
Safe and Efficient: The gear mechanism allows for controlled, steady operation, reducing the risk of water hammer and protecting valve internals from abrupt stress.
2. Resilient EPDM Seat for Bubble-Tight Sealing & Long Life
Ensures dependable, zero-leakage shut-off across a wide range of services.
Superior Elastic Seal: The **Ethylene Propylene Diene Monomer (EPDM)** seat provides excellent elastic recovery, creating a reliable, bubble-tight seal against the metal wedge, even after numerous cycles.
Excellent Media Compatibility: EPDM offers outstanding resistance to water, weathering, and a broad range of chemicals, making it ideal for potable water, wastewater, and various industrial fluids within its temperature range.
Reduced Wear & Maintenance: The resilient seat acts as a cushion, reducing wear on both the seat and the wedge, which extends service intervals and lowers the total cost of ownership.
3. Clear Rising Stem Design for Immediate Visual Indication
Provides unambiguous valve position feedback for enhanced system safety and management.
Instant Status Verification: The **rising stem (OS&Y)** design offers a clear, at-a-glance visual confirmation of the valve position—stem raised indicates open, stem lowered indicates closed—crucial for safety in complex piping systems.
Packaging Protection: The stem threads are located outside the valve body and flow path, protecting them from corrosive or abrasive media and ensuring smooth operation over the valve's lifetime.
Easy Maintenance: The external stem design simplifies lubrication and inspection, facilitating easier preventative maintenance.
4. Robust Full-Bore Design for Minimal Flow Restriction
Built for efficient flow with maximum durability.
Unobstructed Flow Path: The valve provides a **full port (full bore)** design when fully open, allowing pigging and minimizing pressure drop, which translates to energy savings in pumping systems.
Durable Material Construction: The **Ductile Iron (GGG40) body and wedge** provide high strength, excellent impact resistance, and good corrosion resistance, suitable for a wide array of industrial environments.
Flanged End Connections: The integral **flanged ends** (e.g., EN1092, AS2129, ANSI B16.1) ensure a strong, rigid, and leak-proof connection to the pipeline, ideal for permanent installations.
