Komatsu Excavator Relief Valve – Pressure Reducing Valve

The Komatsu excavator relief valve is a hydraulic pressure-reducing valve designed to protect the hydraulic system from excessive pressure. Its standard operating pressure ranges from 250 to 280 bar and can be precisely adjusted via the control screw. The valve body is made of high-strength alloy steel with anti-corrosion coating and can withstand burst pressures up to 400 bar. The inlet and outlet ports have a diameter of 25 millimeters, allowing hydraulic oil flow up to 320 L/min. The internal design includes durable springs and high-pressure-resistant sealing components, extending the valves service life to over 10,000 operating hours.

This relief valve can be directly installed in the boom and bucket hydraulic circuits and performs reliably under heavy, continuous operation. Its precise operation prevents damage to pumps and hydraulic cylinders, ensuring system safety and durability. The valve weighs 3.2 kilograms and measures 180 millimeters in length, facilitating easy installation. Its robust design withstands vibration and shock, operating in temperatures from -20 to 80°C, with simple and quick maintenance. Stable performance under variable pressures maximizes efficiency and the overall hydraulic system lifespan.

Mahab safety relief valve

The Mahab safety relief valve is designed to protect pressurized systems and is constructed from ductile iron GGG40 with an electrostatic epoxy coating. It is available in nominal diameters from 25 to 300 millimeters and can withstand pressures up to 25 bar. The internal spring is made of stainless alloy steel with a tensile strength above 850 MPa, allowing opening pressure adjustment between 1 and 20 bar. The seat and disc are made of stainless steel 304 with NBR or EPDM sealing to ensure leak-free performance. The flanged design complies with EN 1092-2 standard, and the valve operates at temperatures up to 120°C.

The Mahab safety relief valve operates automatically to release excess pressure and prevent equipment damage. Moving parts are manufactured with ±0.2 mm precision, and performance testing is carried out at 1.5 times the nominal pressure. The valve weighs approximately 28 kg at 100 mm size. Its self-return mechanism enables quick closure after pressure normalization. A 250-micron powder epoxy coating provides excellent resistance to wear and chemicals. This valve is widely used in water, steam, petrochemical, and thermal systems.
