Things To Consider

Cross-Reference Alternatives

Conrader MPNs cross individual references to the equivalent Dixon, Honeywell, AME and Anvil for categories like pneumatic system components, pressure & control valves and pipe & tubing. So, if you're looking for a competitor item that is either out of stock or obsolete, chances are Raptor Supplies has the equivalent Conrader products available.


These Conrader products range from small to large sizes. They may require careful packaging as some items might get damaged while shipping. Hence, these Conrader items are delivered by courier shipment and air freight for minimum downtime.

About Conrader

The company's product line includes throttle controls, as well as check, safety relief and micro & unloader valves. Conradar air compressor control valves are designed to drain excess fluid to the tank (with little or no pressure) to prevent pumps and system components from surge shock damage. These unloader valves feature a maximum working pressure of 175 psi and have a brass body featuring stainless-steel ball and spring mechanism. They have a maximum operating temperature of 500 degrees Fahrenheit and a maximum flow rate of 60 cfm. The company's soft seat safety valves protect pneumatic systems from damage due to overpressure. These Conrader relief valves feature a silicon seal, brass body, stainless steel spring and set pressure range of 25-250 psig.

Major Trade Names

Micro Valves

Micro Valves

The brand's Micro Valves feature a unique, over-centre snap-action for a quick response and have no sliding seals, packing or tight-fitting moving parts to leak or wear out. They are immersion tested to ensure zero leakage under pressure and can withstand abrasive-bearing fluids. With all ports havi...

ng some connection, external contaminants like dirt & grit will not affect tight seating and will not cause the valve to stick.

D-Series Discharge Valves

D-Series Discharge Valves

Conrader D-Series discharge valves are suitable for constant-speed applications where intake unloaders are not present. They feature a plot device that sends a signal to open the valve at the set unload pressure and close it at the pilot device's set load pressure to return the pressure to normal sp...

eed. They are available with discharge inlet sizes ranging between 1/8 and 3/4 inches.

In-Tank Check Valves

In-Tank Check Valves

These valves are designed for compressed gas and pneumatic systems. They open to allow flow in one direction and close when the flow stops or reverses. They feature brass bodies, reinforced PTFE seals, male NPT outlet connections, a maximum operating temperature of 450 degrees F and flow rates up to...

150 SCFM.

Hard Seat Safety Valves

Hard Seat Safety Valves

Conrader safety valves feature a metal-to-metal seal to protect air compressors from overpressure damage. They are fatigue resistant, offer the best chemical compatibility and can withstand high temperatures and pressures than elastomer seals. They are available in 3/8 to 1 inch connection sizes

Conrader Competitive Advantages

Smart Start Inlet Control Filter

Smart Start Inlet Control Filter

This filter allow compressors to reach full speed before running under loaded conditions, reducing amperage draw on start-up and eliminating tripped circuit breakers. It compensates for starting voltage drops and allows the usage of multiple tools on the same circuit. This integral inlet filter provides a barrier between worksite contamination and ...

compressor and also improves cold weather & extension cord starting characteristics. It is composed of Nylon material with foamed elements to withstand a maximum operating temperature of 300 degrees F.

Frequently Asked Questions

What is the function of a throttle control?

Conrader throttle controls are suitable for controlling the engine speed of gasoline and diesel engine-driven compressors. They keep the engine at the operational speed until they receive a pressure signal and instantly throttle down the engine until the pressure signal is released.

What is the function of the spring and ball mechanism in pressure unloaders?

The spring and ball mechanism diverts the flow of liquid from the spray nozzle and sends it in a continuous cycle from the outlet side to the inlet side of the pump system. It happens until the operator pulls the trigger gun to stop the process.

How to adjust the unloader valve?

  • Ensure the pressure washer is on a flat surface.
  • Start the engine and keep it at 3700 rpm before load and 3400 rpm under the load.
  • Remove the nylon lock inside the unloader valve and shut off the pressure-adjusting nozzle.
  • Remove the washer and spring from the unloader valve. A threaded piston with two lock nuts is exposed.
  • Tighten the nuts with a wrench.
  • Apply three threads off the bottom and put the washer, spring and nut back in place.
