About CONRADER

Conrader is a manufacturer of pneumatic safety valves and compressor controls, with a product history that includes the development of soft-seat safety valve designs for compressed air systems. The brand's catalog centers on valves that protect pneumatic circuits, receivers, and compressors from overpressure events. 3G Electric supplies Conrader soft-seat pneumatic safety valves and related compressor control components to industrial buyers worldwide, with multiple SKUs available for direct quotation and logistics support.

The core product family in the Conrader line is the soft-seat pneumatic safety valve. These valves use a brass body and a silicone seat or seal, a combination selected for repeated reseating and resistance to sticking in air service. The soft seat is intended to provide a tighter seal at set pressure than a metal-to-metal seat, which reduces leakage after a relief event. Available inlet and outlet sizes in the supplied range include 1/8 in, 1/4 in, 1/2 in, and 3/4 in NPT, with male NPT inlet and female NPT outlet configurations. Set pressures vary by model number; for example, the SRV250 series covers 1/4 in connections with set points such as 50, 75, 125, 175, and 250, while the SRV390 and SRV530 series cover 1/2 in and 3/4 in connections respectively. The valves are used with air and inert gases in compressed air systems, pneumatic circuits, compressors, receivers, and tanks.

Conrader valves are specified by connection size, set pressure, and seat material. The brass construction provides corrosion resistance in typical plant air environments, and the silicone seat is compatible with the temperature ranges common to compressed air systems. Because these are safety devices, correct sizing and set pressure selection are critical: the valve must be rated for the system's maximum allowable working pressure and flow capacity. 3G Electric supports the Conrader line by stocking multiple part numbers across the size and pressure range, providing manufacturer part numbers and specifications for verification, and coordinating global shipping. Buyers can request quotations for specific SKUs, including SRV250-14-50 SST, SRV250-14-250 SST, SRV530-34-125 SST, SRV250-18-75-SST, SRV530-34-175 sst, srv250-14-175 SST, SRV250-14 125 SST, and srv390-12-75 sst, among others. For plant engineers and maintenance managers, this means access to replacement safety valves that match existing Conrader installations without requiring a change in piping or set pressure. For procurement specialists, 3G Electric provides a single point of contact for multiple Conrader SKUs, reducing the number of suppliers needed for compressed air safety components. The product data supplied includes connection type, body material, seat material, and manufacturer part number, allowing cross-referencing against existing bills of materials or nameplate data. 3G Electric does not manufacture these valves; it distributes them as part of its industrial equipment catalog. All technical specifications should be confirmed against the manufacturer's current datasheet before installation, particularly for safety-critical applications where set pressure and flow capacity must meet applicable codes and standards.

Common Applications

  • Compressed air systems — Conrader SRV250 series soft-seat safety valves with 1/4 in NPT connections for overpressure protection on receivers and pneumatic circuits
  • Reciprocating air compressors — Conrader SRV390-12-75 sst with 1/2 in NPT inlet and outlet for relieving overpressure in compressor discharge lines
  • Receiver tanks and pressure vessels — Conrader SRV530 series with 3/4 in NPT connections for protecting tanks from exceeding maximum allowable working pressure
  • Pneumatic control panels — Conrader SRV250-18-75-SST with 1/8 in NPT connections for compact overpressure protection in instrument air circuits
  • Inert gas systems — Conrader soft-seat safety valves with silicone seals for use with nitrogen and other inert gases in industrial processes
  • Maintenance and replacement — Conrader soft-seat safety valves in multiple set pressures (50, 75, 125, 175, 250) for direct replacement of existing valves without piping changes

Frequently asked questions

Common questions about CONRADER from 3G Electric.

What is the difference between a Conrader soft-seat safety valve and a metal-seat safety valve?

Conrader soft-seat safety valves use a silicone seat or seal against a brass body, while metal-seat valves use metal-to-metal contact. The soft seat is designed to provide a tighter seal at set pressure and reduce leakage after a relief event. This can be advantageous in compressed air systems where minor leakage after reseating would waste energy or cause pressure loss. Soft-seat valves are typically used with air and inert gases within the temperature limits of the silicone seat material. Selection should account for the specific set pressure, connection size, and flow capacity required by the system.

What sizes and set pressures are available in the Conrader SRV250 series?

The Conrader SRV250 series includes soft-seat pneumatic safety valves with 1/4 in male NPT inlet and 1/4 in female NPT outlet. Set pressures in the supplied range include 50, 75, 125, 175, and 250, as indicated by model numbers such as SRV250-14-50 SST, SRV250-14-250 SST, srv250-14-175 SST, and SRV250-14 125 SST. The series also includes a 1/8 in size, SRV250-18-75-SST, with a 75 set pressure. All use a brass body and silicone seat. Buyers should verify the required set pressure and connection size against the system's maximum allowable working pressure and the manufacturer's current datasheet.

Can Conrader safety valves be used with gases other than air?

Conrader soft-seat safety valves are described for use with air and inert gases. The silicone seat material and brass body are compatible with many common industrial gases, but compatibility depends on the specific gas, temperature, and concentration. For oxygen, flammable gases, or corrosive media, additional evaluation is required. The valve's set pressure and flow capacity must also be suitable for the gas service. Consult the manufacturer's datasheet for the specific model and confirm compatibility with the intended gas before installation. 3G Electric can provide the manufacturer part number and available specifications for review.

How do I select the correct Conrader safety valve for my compressor or receiver tank?

Selection requires the system's maximum allowable working pressure, the required relief flow capacity, and the connection size and type. The valve set pressure must not exceed the maximum allowable working pressure of the protected equipment. The inlet size should match the piping or vessel connection, typically male NPT for Conrader valves. The outlet size is usually the same as the inlet in the supplied range. Flow capacity must be sufficient to relieve the maximum input from the compressor or other pressure source. Use the manufacturer's flow curves and set pressure ratings to confirm the model. 3G Electric supplies multiple Conrader SKUs and can quote based on the required specifications.

What materials are used in Conrader soft-seat pneumatic safety valves?

Conrader soft-seat pneumatic safety valves in the supplied range use a brass body and a silicone seat or seal. Brass provides corrosion resistance in typical compressed air environments. The silicone seat is intended to provide a tight seal and resist sticking. The inlet and outlet connections are also brass. These materials are suitable for air and inert gases within the temperature limits of the silicone. For specific temperature ratings and pressure limits, refer to the manufacturer's datasheet for the exact model number. 3G Electric lists the body material, seat material, and connection type for each SKU.
