Material: Stainless Steel

     Z15W
Internal thread connection gate valve is suitable for water, oil, gas, and certain corrosive liquid media within a temperature range of -20-232-350℃.

Model: Z41

Diameter: 15～600mm

Pressure: 1.6-16.0Mpa

Material: Cast Steel, Stainless Steel, Chrome Molybdenum Steel

     High and medium pressure flange-connected gate valves are suitable for various pipeline systems in petroleum, chemical, hydraulic, and thermal power plants to shut off or connect pipeline media. Z41 flange gate valves are suitable for media such as water, oil, steam, and acids, alkalis, ammonia, urea, sulfur-containing natural gas, etc.

Model: BZ41H/W

Diameter: 40～300mm

Pressure: 1.6MPa～2.5MPa

Material: Cast Steel, Stainless Steel

     BZ41H/W gate valves are mainly used in petroleum, chemical, metallurgical, pharmaceutical, and other systems. The jacket of the BZ41 gate valve is welded between the two flanges, with connection ports on the side and bottom of the valve. Steam or other thermal insulation media can freely flow through the jacket, ensuring that viscous media can flow smoothly through the valve.

Model: WZ41H/Y

Diameter: 15～200mm

Pressure: 1.0～6.0MPa

Material: Cast Steel, Stainless Steel

     The bellows gate valve uses a bellows and packing dual sealing structure to ensure leak-free sealing at the valve stem. The WZ41H/Y bellows gate valve is particularly suitable for pipelines carrying flammable, explosive, toxic, and valuable media.

Model: PZ41H/X

Diameter: 50～500mm

Pressure: 1.6-6.4Mpa

Material: Cast Steel, Stainless Steel

     PZ41H gate valves are suitable for slag discharge systems in thermal power plant hydraulic systems and water conservancy projects to shut off or connect mixtures of ash-water and slag-water in pipelines.

Model: Z43H/X

Diameter: 50～600mm

Pressure: 1.6～10.0MPa

Material: Cast Steel, Stainless Steel

     Flat gate valves are suitable for petroleum, natural gas, water, oil, and other pipelines to shut off or connect the medium in the pipeline.

Model: Z44X/RRHX

Diameter: 50～400mm

Pressure: 1.0～2.5MPa

Material: Cast Iron, Cast Steel

     In addition to the advantages of resilient seated gate valves, the rising stem seated gate valve allows for visual indication of valve opening, with quick and reliable opening and closing. Therefore, the Z44X rising stem gate valve is commonly used in fire protection and industrial systems, typically installed at higher positions above the ground.

Model: Z45X/RVHX

Diameter: 50～400mm

Pressure: 1.0～2.5MPa

Material: Cast Iron, Cast Steel

    Non-rising stem resilient seated gate valves can be widely used in tap water, sewage, construction, petroleum, chemical, food, pharmaceutical, light textile, electric power, shipping, metallurgy, energy systems, and other fluid pipelines as regulating and shut-off devices.

Model: Z641

Diameter: 40～600mm

Pressure: 1.6-6.4Mpa

Material: Cast Iron, Cast Steel, Stainless Steel

     The new series of pneumatic piston gate valves (referred to as pneumatic gate valves) are widely used in industrial fields due to their excellent shut-off performance. The temperature range is from -196℃ to 500℃.

Model: Z941

Diameter: 40～500mm

Pressure: 1.0～16.0MPa

Material: Cast Iron, Cast Steel, Stainless Steel

     Flange-connected steel gate valves are suitable for various media such as water, steam, oil, acetic acid, strongly oxidizing media, and urea. Drive methods include manual, bevel gear, and electric.

Model: DS/Z44H

Diameter: 50～600mm

Pressure: 1.6MPa～10.0MPa

Material: Cast Steel, Stainless Steel, Chrome Molybdenum Steel

     Water seal gate valves are suitable for pipelines with a nominal pressure of 100MPa, working temperature of 425℃, and media such as water, steam, oil, and non-corrosive gases, used as shut-off devices. The DS/Z44H gate valve is particularly suitable for vacuum condensation systems in thermal power plant turbines.

Model: DS/Z64H

Diameter: 1.6MPa～10.0MPa

Pressure: 1.6MPa～10.0MPa

Material: Cast Steel, Stainless Steel, Chrome Molybdenum Steel

     Water seal gate valves are suitable for pipelines with a working temperature of 425℃, nominal pressure of 100MPa, and media such as oil, steam, water, and non-corrosive gases, used as shut-off devices. The DS/Z64H water seal gate valve is particularly suitable for vacuum condensation systems in thermal power plant turbines.
