Hydraulic valve blocks in marine hydraulics are compact units that control fluid flow in ship systems. They integrate multiple valves to manage direction, pressure, and flow for efficient operation. Designed for durability, they withstand harsh marine environments and ensure reliable performance.

Size: Typically ranges from 50 mm to 500 mm in length, width, and height, depending on application.

Grade: Commonly complies with ISO 4401, DIN 24300, or ANSI/B93.7 standards.

Viscosity: Operates with hydraulic fluids of 15-68 cSt at 40°C (ISO VG 22 to VG 68).

Buoyancy: Not typically applicable; designed for fixed marine installations.

Material: Cast iron, ductile iron, or stainless steel (AISI 316 for corrosion resistance).

Pressure Rating: 210 bar to 350 bar (standard), up to 420 bar (high-pressure variants).

Temperature Range: -20°C to +80°C (standard), -40°C to +120°C (specialized).

Port Size: SAE, BSPP, or NPT threads, typically 1/4" to 2".

Seals: Nitrile (NBR), Fluorocarbon (FKM), or Ethylene Propylene (EPDM) for seawater compatibility.

Finish: Corrosion-resistant coatings or passivation for marine environments.

Yes, Hydraulic Valve Blocks and Marine Hydraulics typically comply with maritime standards such as ISO 4413, ISO 4401, and DNV/GL standards, depending on the specific product and manufacturer.
