ANSI Gate Valve
Models: Z40W, Z41H, Z41Y
Actuation: Manual, Pneumatic, Electric, Bevel Gear
Connection Type: Flanged, Welded
Structure: Wedge Gate
Sealing Type: Metal-to-Metal (Hard Sealing)
Pressure Range: 150–2500 LB
Nominal Diameter: DN15–1000
Common Materials: Cast Iron, Cast Steel, Stainless Steel
Technical Features:
Standard Compliance: Designed and manufactured in accordance with ANSI B16.34 and API standards (API600/602/603).
Compact and Robust: Small footprint, rigid structure, reliable and safe sealing.
Elastic Wedge Gate: The gate compensates automatically for valve body deformation caused by abnormal loads or temperature changes, ensuring consistent sealing without generating wedge distortion.
Ease of Operation: For valves with nominal diameter ≥ NPS 10-11, pressure class 400 LB, or nominal diameter ≥ NPS 6-11, pressure class 150–2500 LB, manual valves are equipped with rolling bearings in the actuator for smooth operation.
Material Flexibility: Body, internal parts, packing, gaskets, and fasteners can be selected according to user requirements or actual operating conditions.
Replaceable Seats: Optional replaceable valve seats can be paired with different sealing materials to meet operating conditions and extend service life.
