What kind of safety valves does dresser make?
What kind of safety valves does dresser make?
Dresser Valves The range includes a complete line of safety valves, including spring-loaded and pilot operated designs. Dresser Valves also delivers reciprocating and rotary valves, field instruments and regulators.
What causes excessive wear on a hydraulic system?
Excessive wear may be due to oil contamination. 2. Check for dirt, gummy deposits or air leaks as above. Check for misalignment, worn parts or defective packing. 3. Viscosity of oil too high or pour point too high at starting temperature. Change to oil with lower viscosity or better viscosity index and lower pour point.
What causes high pressure on a crawler loader?
I would first look at the relief valves located under the torque convertor housing. It is possible the one or more of the valves is sticking, causing the high pressure. The plungers/valve pistons should move freely in their bores. Thank you so much for the advise and I will check that out an then let you know what I find.

Can a clogged intake line cause a hydraulic failure?
In extreme cases, cavitation can cause mechanical failure of system components. While cavitation can occur just about anywhere within a hydraulic circuit, it commonly occurs at the pump. A clogged inlet strainer or restricted intake line will cause the fluid in the intake line to vaporize.

What are the symptoms of a hydraulic system problem?
A reduction in machine performance is often the first indication that there is something wrong with a hydraulic system. This usually manifests itself in longer cycle times or slow operation. It is important to remember that in a hydraulic system, flow determines actuator speed and response. Therefore, a loss of speed indicates a loss of flow.
