CONRADER

Conrader is a manufacturer of pneumatic safety valves, check valves, and related components, with a product line focused on overpressure protection and flow control in compressed air and gas systems. The company's catalog includes hard seat and soft seat safety valves, in-line check valves, and accessories designed for industrial, commercial, and mobile equipment applications. Conrader valves are constructed from materials such as brass and stainless steel, with seat options including silicone for soft seat variants and stainless steel for hard seat variants. Port sizes range from 1/8 inch to 2 inch NPT, and pressure ratings extend up to 250 psi for check valves and up to 390 psi for certain safety valve models. The product range covers preset and adjustable pressure settings, with configurations available in male NPT inlet and female NPT outlet orientations. Conrader components are used in pneumatic systems where reliable pressure relief and backflow prevention are required, including air compressors, pneumatic tools, and process control equipment. 3G Electric stocks over 500 SKUs of Conrader products, providing datasheets and logistics support for global procurement. The inventory includes both common and specialized configurations, enabling engineers and maintenance managers to source replacement valves and new installations from a single distributor. Each SKU is documented with specifications covering material, connection type, pressure rating, and seat material, allowing technical buyers to match components to system requirements without ambiguity.

Frequently asked questions

Common questions about CONRADER from 3G Electric.

What is the difference between Conrader hard seat and soft seat safety valves?

Conrader hard seat safety valves use a metal-to-metal seal, typically stainless steel against brass, providing durability in high-cycle or high-temperature applications. Soft seat valves incorporate a silicone seal, which offers better sealing at lower pressures and is less prone to leakage in systems with particulate contamination. The choice depends on operating pressure, temperature, and media cleanliness.

What materials are Conrader check valves and safety valves available in?

Conrader check valves are constructed from brass with brass internals. Safety valves are available in brass bodies with either brass or stainless steel internals for hard seat models, or brass bodies with silicone seats for soft seat models. Stainless steel construction is also offered for certain safety valve configurations, particularly in the SRH series.

What pressure ratings do Conrader safety valves cover?

Conrader safety valves are available with preset pressure settings ranging from 50 psi to 390 psi, depending on the model. For example, the SRV250 series is rated up to 250 psi, while the SRH375 series can handle up to 375 psi. Check valves are rated for a maximum pressure of 250 psi. Always verify the specific model's rating before installation.

What connection sizes are available for Conrader valves?

Conrader safety valves and check valves are offered in NPT connection sizes from 1/8 inch to 2 inch. Inlet connections are typically male NPT, while outlets are female NPT. For example, the GV2 check valve has 2 inch female NPT on both ends, and the SRV250-1/8-CE-060 safety valve has a 1/8 inch male NPT inlet and 3/8 inch female NPT outlet.

Can Conrader safety valves be used in liquid service?

Conrader safety valves are designed for pneumatic service, specifically compressed air and non-corrosive gases. They are not typically rated for liquid service unless explicitly stated in the product specifications. For liquid overpressure protection, a valve with appropriate materials and certifications should be selected.
