The Yibengfa name operates as a valve industry platform rather than a single manufacturing brand, but the data below reflects the standard Z41H-16C specification shared across reputable Chinese valve makers and is directly applicable for selection and procurement.The main gate valve product names of China gate valve Network include:Electric Slurry Valve,Electric Flange Gate Valve,Fire Special Signal Relisient Seat Seal Gate Valve,Fire Special Rising Stem Resilient Seat Seal Gate Valve,Forged Steel Socket Welding Valve,Forged Steel Flange Gate Valve,GB Bellows Wedge Gate Valve,High Temperature & pressure Power Station Gate Valve,Inside Screw Non-rising Stem Wedge Gate Valve,Insulation Jacket Gate Valve,Lined Gate Valve,MZ44W Rising Stem Gas Quick Open&close Parallel,MZ48W Manual Non-rising Stem City Gas Quick Gate Valve,Manual Knife-shaped Gate Valve,Manual Slurry Valve,Manual Wedge Copper Gate Valve.

Technical Parameters

The Z41H-16C carries a nominal pressure rating of PN16 (1.6 MPa). Shell test pressure is 2.4 MPa, liquid seal test pressure is 1.76 MPa, and air seal test pressure is 0.6 MPa. The applicable temperature range is up to 425 degrees Celsius for water, steam, and oil media. The body and bonnet are cast carbon steel (WCB). The wedge and seat sealing surfaces are hardfaced with hard alloy, and the stem is chrome stainless steel. The stem nut is aluminum bronze, and the packing is graphite asbestos. The design standard is GB/T 12234, structural length follows GB/T 12221, flange connection follows JB/T 79, and testing follows JB/T 9092. The rising stem design provides direct visual indication of the disc position, and the wedge gate construction ensures reliable sealing.

Dimensions

Dimensions are given in millimeters, with L as face-to-face length, D as flange outer diameter, D1 as bolt circle diameter, H as valve height, and D0 as handwheel diameter. For DN50: L 230, D 160, D1 125, H 358, D0 240. DN80: L 320, D 195, D1 160, H 433, D0 280. DN100: L 350, D 215, D1 180, H 502, D0 320. DN150: L 480, D 280, D1 240, H 676, D0 360.
