OverviewThe Z41W-150LB API Standard Gate Valve (150LB Pressure Class) is a rising stem gate valve designed and manufactured according to American standards (such as API and ANSI). It controls fluid flow by vertically lifting or lowering the gate plate. During operation, the valve stem moves in tandem with the gate plate, providing clear position indication. The valve's core feature lies in its “W” designation, indicating a sealing surface machined directly from the valve body material. This typically forms a metal-to-metal hard seal pairing with the metal gate. Rated at 150LB pressure, it meets corresponding American standard pressure-temperature ratings and is suitable for various demanding industrial applications. Widely adopted in petroleum, chemical, power generation, natural gas, and shipbuilding industries adhering to American standards or requiring international compatibility, this valve reliably serves as shut-off equipment in pipelines transporting water, steam, petroleum products, natural gas, and non-aggressive media. It plays a critical role in applications demanding strict isolation and complex operating conditions.Z41W-150LB API Standard Gate Valve (150LB Pressure Class)

OverviewThe Z43WF stainless steel flat gate valve is a straight-through valve manufactured from stainless steel. It controls fluid flow by vertically lifting a flat gate plate between two parallel seats. Typically featuring a “dual gate plate with elastic expansion” design, this valve automatically compensates for wear on the sealing surfaces during closure. The “F” designation indicates that the seat sealing surface is machined directly from the valve body material or overlaid with other materials, forming a metal-to-metal hard seal with the stainless steel gate plate. This configuration is suitable for high-temperature, high-pressure, and applications requiring high cleanliness standards. This product is widely used in pipeline systems across petrochemical, natural gas transmission, food and pharmaceutical, marine, and light industrial sectors. It is particularly suitable for conveying natural gas, refined oil, water, steam, and various non-corrosive media. It serves as critical shut-off equipment requiring high flow capacity, reliable sealing, and stringent material cleanliness standards.Z43WF Stainless Steel Flat Gate Valve Product Drawing

Z941W electric gate valve is a rising stem wedge gate valve driven by an electric actuator and connected by a flange.

OverviewZ543Y Parallel Slide Gate Valve with Hardfaced Seats is a straight-through valve driven by bevel gear, which realizes the on-off of fluid through the vertical rise and fall of a flat gate between two parallel valve seats. Its "Y" represents that the sealing surface is overlaid with hard alloy (such as Stellite) or other wear-resistant materials to form a high-performance metal hard seal pair together with the ram of the same surfacing hard alloy. The introduction of bevel gear transmission mechanism provides huge operating torque, making the opening and closing of large-diameter and high-pressure valves labor-saving and reliable. The product is mainly used in heavy industrial fields such as oil and natural gas long-distance pipelines, refineries, chemical plants, power stations, offshore platforms, etc. It is applicable to the transmission of crude oil, refined oil, natural gas, water, steam and other media, especially suitable for high temperature, high pressure, high wear and critical pipe sections requiring strict cutting as the main block valve.
