Product Description

Stainless Shut Off Valve - Professional Industrial Solution

ZTVK's stainless shut off valve conveys enterprise-grade execution with remarkable unwavering quality over requesting mechanical applications. Our progressed plan highlights a weight run from PN1.6 to 6.4MPa (ANSI150LB-600LB) and ostensible breadths crossing DN15-DN400. The valve joins premium body materials counting CF8, CF8M, CF3, and CF3M stainless steel arrangements. With working temperatures coming to 450°C for metal seats and industry-leading spillage levels (ANSI VI for delicate seats, ANSI IV for metal seats), this valve guarantees ideal stream control and framework keenness for your basic processes.

Key Features and Benefits

Superior Design Architecture

Our valves include a opposite valve stem hub to the situate fixing surface, giving especially dependable cutting activity. The compact stroke plan diminishes generally valve tallness whereas keeping up basic keenness. This designing approach makes our stainless closed off valve perfect for applications requiring exact medium control and throttling capabilities.

Material Excellence

The valve body construction utilizes high-grade stainless steel materials including:

CF8 Stainless Steel: Excellent general-purpose corrosion resistance
CF8M Stainless Steel: Enhanced molybdenum content for superior chemical resistance
CF3 and CF3M Options: Low-carbon variants for specialized applications

These materials provide superior corrosion resistance compared to standard cast iron alternatives, ensuring long-term reliability in harsh environments.

Flexible Connection Options

Multiple connection configurations accommodate diverse installation requirements:

RF (Raised Face)
RJ (Ring Joint)
FF (Flat Face)
LG (Large Groove)
Flange options: PN16 convex surface, PN40/64 concave-convex surface

Dual Seat Technology

Soft Seat Configuration:

Temperature range: -20°C to +250°C
Leakage level: ANSI Class VI
Ideal for standard industrial applications

Metal Seat Configuration:

Temperature range: -60°C to +450°C
Leakage level: ANSI Class IV
Perfect for extreme temperature environments

Operating Principles

The valve operates through valve stem pressure, creating tight contact between the disc sealing surface and seat sealing surface. This mechanism effectively blocks medium flow when closed. The unidirectional flow design ensures proper installation orientation and consistent performance.

During operation, minimal friction occurs between sealing surfaces, contributing to extended service life. The relatively short disc stroke enables compact installation while maintaining excellent sealing reliability.

Industry Applications

Our stainless shut off valve serves multiple industrial sectors:

Petrochemical Processing: Chemical resistance for aggressive media
Power Generation: High-pressure steam applications
Food & Pharmaceutical: Sanitary design compliance
Water Treatment: Corrosion resistance for treatment chemicals
Nuclear Industry: Stringent quality and safety requirements
