Product Description

Product Description

1. Compact & Space-Saving Design
Features a slim, lightweight structure (1/3~1/2 the weight of gate valves/ball valves of the same size) with a short face-to-face dimension, minimizing installation space requirements. Ideal for tight-layout systems (e.g., pipeline skids, confined industrial areas) and reducing transportation/installation costs.
One-piece or two-piece body construction (wafer, lug, or flanged ends) ensures easy integration with existing pipelines, compatible with standard pipe connections (ANSI, DIN, JIS, GB).
2. Excellent Flow Performance & Energy Efficiency
Full-bore or reduced-bore design (optional) with a streamlined disc that minimizes flow resistance (low pressure drop). Delivers high Cv values (flow coefficient) for optimal fluid circulation, reducing pump energy consumption by up to 30% compared to traditional valves in large-flow applications.
Smooth disc rotation (90° full stroke) ensures consistent flow control, suitable for both on/off service and throttling operations (for soft-seal models, throttling range: 30%~70% open).
3. Reliable Sealing Performance for Diverse Media
Dual sealing options to meet different working conditions:
Soft Seal: Adopts high-performance elastomers (PTFE, EPDM) for bubble-tight sealing (leakage rate ≤ Class VI) at low to medium pressures (PN10~PN25, Class 150). Resists corrosion from chemicals, wastewater, and neutral fluids, ensuring zero external/internal leakage.
Metal-to-Metal Hard Seal: Precision-machined stainless steel (SS304/316) or alloy steel (Inconel, Hastelloy) disc and seat for high-temperature (up to 600℃) and high-pressure (PN40~PN100, Class 300~600) applications. Suitable for steam, superheated water, and abrasive media (e.g., slurry, dust-laden gas).
Self-cleaning disc design prevents media buildup (e.g., sludge, particles) on the sealing surface, maintaining long-term sealing integrity.
4. Durable & Corrosion-Resistant Materials
Body materials available: Cast iron (GG25), ductile iron (GGG40), carbon steel (WCB), stainless steel (SS304/316/L), and duplex stainless steel (2205). All materials undergo anti-corrosion treatment (epoxy coating, passivation) for service in harsh environments (e.g., marine, chemical plants, wastewater treatment).
