Role of Rolls Royce’s Pressure Control Valves

Rolls Royce Car

Rolls Royce is the highest caliber of luxury vehicle available on the market. As an owner of one of these majestic beauties, you know that they offer a superb driving experience that is, quite literally, unmatched. Driving down the road, these cars feel like you’re riding on a cloud. The quality and craftsmanship are superior, but that doesn’t mean a Rolls is impervious to part failures. Regular maintenance is especially important for these cars in order to maintain optimal performance and ensure the value of the vehicle over its lifetime. In this article, we will talk about the purpose of Rolls Royce pressure control valves. Let’s get started.

Different Valves for Different Functions

A Rolls Royce actually has multiple pressure valves for various purposes. There are pressure control valves for the air suspension, braking, and driver safety systems. No matter what system it’s in, a pressure valve serves one primary purpose: to help the system maintain a certain pressure. Whether it’s helping prevent pressure from climbing too high for safety reasons or keeping pressure high enough that the system can function, you can see why it’s important for each of these valves to be working properly.

A few of the pressure control valves found in your Rolls Royce include:

Suspension Pressure Valves

Newer Rolls Royce models all make use of an air-cushion suspension system, helping provide you with the smooth ride you associate with the brand. To help maintain the pressure needed to keep the car level and absorb impacts from the road, air spring pressure valves are needed to keep the proper pressure in the air spring. If these valves begin to fail, you may notice that your Rolls is sitting lower than it should, possibly unevenly if only one side is failing.

Crankcase Ventilation Valve

The crankcase of your Rolls is essential to its operation, as it helps remove exhaust fumes from the vehicle. The one-way pressure valve in this part ensures the gases are moving to the next stage of the exhaust system where they can be safely removed. If this valve goes bad, your Rolls Royce may backfire or experience a hard start.

Height Control Valves

Certain older Rolls Royce models were equipped with height control valves in the front suspension. Like the suspension pressure valves, they can fail over time and may need to be replaced or reconditioned.

Oil Pressure Valve

Every vehicle needs oil, and your Rolls is no exception. Oil both lubricates engine parts and helps keep the temperature in a safe range. A properly pressurized oil system ensures the oil gets where it needs to be. If you notice an oil leak or are getting low oil pressure alerts, your oil pressure valve may need to be replaced.

Fuel Pressure Regulator

Like oil, the fuel in your vehicle is also pressurized to help it get where it needs to go. If your fuel pressure regulator stops functioning as it should, you’ll notice a huge difference in your vehicle’s performance, including backfiring, reduced power, or the smell of fuel when you accelerate. If the regulator is failing to hold much pressure at all, you may not even be able to start your vehicle.

Repairing Your Rolls

The valves listed above are just a few of the pressure control valves helping keep your Rolls Royce operating properly. If you notice anything odd or wrong with how your vehicle is operating, it’s important to get it checked out as soon as possible.
