Manual hydraulic valve , Iran
Hydraulic manual valves feature bodies made of high-strength alloy steel or ductile iron. This body undergoes precise heat treatment processes. Their nominal working pressure typically reaches up to 350 bar. Their peak pressure can attain 420 bar. The permissible operating temperature ranges from -20 to +80 degrees Celsius. Standard applicable fluids are mineral-based hydraulic oils. Connections are usually threaded per ISO 6149 or flange-mounted per ISO 4401 standards. Internal sealing is achieved using O-Rings made of NBR or Viton materials. This design minimizes leakage. Valves often feature clear position indicators and an ergonomic handle.
Structurally, these valves are often constructed as high-pressure ball or poppet types. The internal port design is optimized for low hydraulic losses and laminar flow. Valves can be two or three-position and two or three-way configurations. The handles operating torque is typically less than 10 Newton-meters. This torque is designed for comfortable operator use. Their volumetric efficiency is usually reported above 97 percent. High-quality valves possess an internal surface polish of Ra 0.4 micrometers. This polish prevents particle abrasion. All components are protected against corrosion via methods like phosphating or plating.You can order and buy Manual hydraulic valve from Iran by contacting us through whatsaap and email.

Analysis of Advantages and Disadvantages of Using Hydraulic Manual Valves from Iran
Iranian hydraulic manual valves are typically offered at prices 15 to 30% lower than comparable imported models. These valves are usually manufactured for a standard working pressure of 210 bar and an operational temperature range of -20 to 80 degrees Celsius. Their key advantage is rapid access to spare parts and domestic technical support. However, technical drawbacks include an internal leakage rate of approximately 10 to 15 drops per minute and an average useful life of 4000 hours of continuous operation. Furthermore, the dimensional tolerance of their components sometimes deviates by 0.1 mm from the international ISO 4401 standard. This issue negatively impacts system efficiency in high-precision applications.
