welded national standard gate valve
I. Introduction:
Z61H, Z61Y, Z61W type PN100~PN160 socket weld wedge gate valves: manual operation, socket weld connection, rising stem wedge type rigid single disc. The seat sealing surface materials are alloy (Z61H-100~160, Z61Y-100~160, Z61Y-100P~160P, Z61Y-100I~160I) and stainless steel (Z61H-100P~160P, Z61W-100P~160P). Nominal pressure is PN100~PN160. The valve body materials are carbon steel (Z61H-100~160), stainless steel (Z61H-100P~160P, Z61W-100P~160P, Z61Y-100P~160P) and alloy steel (Z61Y-100~160, Z61Y-100I~160I).
