Frequently asked questions
Common questions about HYTEC from 3G Electric.
What are the typical applications for HYTEC lever-operated directional control valves?
HYTEC lever-operated directional control valves, such as the model 9503, are used in manual hydraulic circuits where an operator needs to direct fluid flow to actuators like cylinders or motors. Common applications include workholding fixtures, machine tool clamping, and mobile equipment controls. These valves are available in two-position, three-way/four-way configurations with 1/4" NPT ports, making them suitable for low-to-medium flow circuits. They are not load-holding rated, so they should not be used in applications requiring positive locking without additional check valves.
What is the pressure rating of HYTEC pilot-operated check valves?
HYTEC pilot-operated check valves, such as the model 100915, are rated to 5,000 psi. They feature SAE-6 9/16-18 UNF inlet and outlet connections and are constructed with a steel body. These valves are designed to allow free flow in one direction and block flow in the reverse direction until pilot pressure is applied. They are commonly used in hydraulic circuits to hold loads in position, such as in vertical cylinder applications or clamping systems.
What are the specifications of HYTEC hollow plunger workholding rams?
HYTEC hollow plunger workholding rams, like the model 351013, have a nominal capacity of 9,945 lb and a nominal stroke length of 2 inches. The retracted height is 3.48 inches, and the plunger diameter is 1.5 inches. These rams are designed for clamping or lifting tasks where a hollow plunger allows for through-hole access or rod passage. They are typically used in workholding fixtures and press applications.
Are HYTEC directional control valves load-holding rated?
No, HYTEC lever-operated directional control valves, such as the model 9503, are specified as 'Not Load Holding.' This means they do not have internal mechanisms to lock the spool in position or prevent movement under load. For applications requiring load holding, engineers should use pilot-operated check valves or counterbalance valves in conjunction with these directional control valves.
What connection types are available for HYTEC hydraulic check valves?
HYTEC pilot-operated check valves, such as the model 100915, use SAE-6 9/16-18 UNF connections for both inlet and outlet. This is a common straight-thread O-ring port type used in industrial hydraulic systems. The steel body construction ensures compatibility with standard hydraulic fluids and pressures up to 5,000 psi.
