Z543Y Parallel Slide Gate Valve with Hardfaced SeatsOverview

Overview

Z543Y 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. It is one of the core equipment to ensure the safe operation of the industrial energy artery.

Z543Y Parallel Slide Gate Valve with Hardfaced SeatsCharacteristic

Features:

Bevel gear labor-saving drive: the bevel gear angle drive mechanism is adopted, with obvious torque increasing effect, which can amplify the hand wheel input force dozens of times, easily drive valves with large diameter and high pressure rating, and support the extension of the operating shaft in vertical or horizontal directions.

High-performance hard seal: "Y" hard alloy sealing surface has extremely high hardness, abrasion resistance and scratch resistance, which is applicable to high temperature, high pressure and harsh working conditions containing tiny particles, and its service life is far more than that of conventional sealing materials.

Full-diameter and low flow resistance: the valve adopts full-diameter design, the flow passage is smooth and straight, basically consistent with the inner diameter of the pipe, the resistance is very small when the fluid passes through, almost no pressure loss is generated, and it is suitable for large-flow transmission pipelines.

Double ram elastic structure: floating double ram design is generally adopted, with built-in elastic elements, which can automatically compensate the clearance caused by temperature and pressure change or slight wear when closing, so as to ensure the reliability of two-way seal.

Solid structure and wide applicability: the valve body is usually forged with carbon steel or alloy steel, with high structural strength. The combination of hard seal and bevel gear drive makes it ideal for heavy industrial applications such as long-distance pipelines, oil fields and power plants.
