Hydraulic filters keep oil clean in hydraulic systems, protecting pumps, valves and cylinders from wear and sticking. Clean oil is the single biggest factor in hydraulic reliability.

Hydraulic Filter Types

• Pressure filters – protect sensitive components
• Return filters – capture wear debris
• Suction strainers – protect pumps
• Spin-on filters – easy replacement
• Replacement elements – OEM interchanges

Choosing a Filter

Select micron rating and beta ratio to meet your ISO cleanliness target, along with pressure rating and flow capacity. Bypass indicators show when to change elements.

Hydraulic O-rings seal fittings, cylinders, valves and pumps in hydraulic systems. The right compound and size stops leaks and holds up under high pressure and temperature.

O-Ring Options

• Nitrile (Buna-N) – standard petroleum oil service
• Viton (FKM) – high temperatures and chemicals
• Polyurethane – high pressure and abrasion resistance
• Backup rings – prevent extrusion
• O-ring kits – assorted sizes for maintenance

Choosing O-Rings

Match size (AS568 or metric), durometer and compound to the fluid, temperature and pressure. Use backup rings above about 1,500 psi.

Compressed air filter elements are the replaceable parts that do the filtering inside compressed air housings. Regular replacement keeps air quality high and pressure drop low.

Element Types

• Particulate elements – remove solids
• Coalescing elements – remove oil and water aerosols
• Activated carbon elements – remove oil vapor
• OEM interchangeable elements – fit major brands

Replacement Tips

Replace elements annually or when pressure drop rises. Have the housing brand and model ready to find the right element.

Turbine flow meters measure liquid flow by counting the rotation of a turbine rotor. They're accurate and responsive in clean, low-viscosity liquids such as water, fuels and light chemicals.

Turbine Meter Features

• High accuracy – suitable for batching and blending
• Wide turndown – broad flow range
• Pulse and analog outputs – connect to totalizers and controls
• Sanitary and stainless versions – food and chemical service

Installation Tips

Provide enough straight pipe upstream and downstream, and install a strainer to protect the rotor. Viscosity changes affect accuracy, so turbines suit consistent, clean fluids.

Centro supplies turbine flow meters for water, fuel and chemical measurement.

Desiccant breathers replace standard reservoir breather caps. They stop moisture and dirt from entering hydraulic and gearbox reservoirs as they breathe.

Benefits

• Moisture removal – silica gel absorbs water
• Particulate filtration – capture airborne dirt
• Color change indication – show when to replace
• Longer oil and component life – reduce contamination

Choosing a Breather

Size by airflow and environmental humidity. Use adapters to fit existing fill ports.

Pressure sensors in automation monitor air, hydraulic and fluid pressure on machines. They confirm clamp pressure, detect leaks and protect equipment.

Sensor Types

• Electronic pressure switches – displays and set points
• Pressure transmitters – analog outputs
• IO-Link pressure sensors – diagnostics and setup
• Vacuum sensors – gripper confirmation

Choosing a Sensor

Select range, output, connection and display options. Compact sensors fit directly on machines.

Centro supplies pressure sensors for automation.

Check valves are mechanical devices designed to allow fluid—whether liquid or gas—to flow in only one direction, preventing backflow that can damage equipment or disrupt system performance. Commonly used in industrial, plumbing, and MRO (maintenance, repair, and operations) systems, they automatically open with forward flow and close when flow reverses. Available in various types like swing, ball, and inline designs, check valves are essential for ensuring system integrity, protecting pumps and compressors, and maintaining operational safety.

Types of Check Valves We Offer:

• Swing Check Valves – Ideal for irrigation and low-pressure systems
• Ball Check Valves – Reliable for wastewater and slurry applications
• Piston Check Valves – Designed for precise flow control in hydraulic systems

We partner with leading manufacturers to provide top-quality materials and engineering in every check valve we supply. Browse our extensive selection and find the perfect check valve for your needs. Order online today or contact our experts for assistance!
