Spool valves can be used in both hydraulics (where the oil is the energy source) or Pneumatics (where the air is the energy source) and their job is to control the flow direction of the energy source by combining or switching the paths through which the oil or air can travel.
People ask also, how much does it cost to replace a spool valve on a Honda Odyssey? Labor costs are estimated between $87 and $110 while parts are priced between $455 and $605.
Also know, how do you replace a spool valve?
Also, what is spool valve assembly? Essentially a spool valve is a cylinder inside a sealed outer case. There are several chambers drilled through the case from one side to the other, these are commonly known as “ports”. … Imagine the example of extending a pneumatic cylinder using a spool valve. The Pneumatic air supply is connected to the inlet port 1.
Likewise, can you drive with a bad VVT solenoid? Can You Drive with a Bad VVT Solenoid? Even though you may technically be able to continue driving with a bad VVT solenoid, the issue can cause damage to additional parts, such as the VVT actuator. So, you should address the issue as soon as possible.

How do you know when VTEC kicks in?
What are the symptoms of a bad VTEC solenoid?
- Check Engine Light comes on. Since today’s modern cars are controlled by an Engine Control Unit (ECU), virtually all individual components are monitored by the ECU.
- Engine oil is dirty.
- Rough engine idle.
- Decrease in fuel economy.
What causes spool valve to leak?
The excessive leakage is the result of the fluid bypassing a piston seal either through a worn seal or a worn cylinder barrel (Figure 1). In spool valves, excessive internal clearances between the spool and the valve body decrease control and stability of the hydraulic circuits and their functions.
What are valve cover gaskets?
What is a valve cover gasket? A valve cover gasket seals the valve cover to the top portion of the engine cylinder head. The gasket prevents motor oil from leaking out as it travels around the camshafts, rockers and valves.
How much does it cost to replace a VTEC solenoid?
The average cost for a Variable Valve Timing Control Solenoid Replacement is between $198 and $253 but can vary from car to car.
How do I know if my VTEC solenoid is working?
What does v Tec stand for?
The VTEC (Variable Valve Timing & Lift Electronic Control) system uses separate camshaft profiles for low and high-end performance, and the engine computer selects between profiles.
What are two types of spool valves?
Spool is of two types namely sliding and rotary. Sliding spool is cylindrical in cross section, and the lands and grooves are also cylindrical. Rotary valves have sphere-like lands and grooves in the form of holes drilled through them.
What is the difference between poppet and spool valve?
“The main difference between a spool and a poppet valve is the construction,” explains Daniella Gonzalez-Olgren, a valve product specialist from Festo. … However, spool valves usually have higher flows than poppet valves within the same footprint.
