CONTROL DEVICES

Control Devices is a manufacturer of pneumatic and compressed-air system protection components, with a product line centered on safety valves, relief valves, and compressor controls. The company's catalog includes soft-seat pneumatic safety valves, vacuum and pressure relief valves, and vacuum relief valves, offered in brass and stainless steel body materials. These products are used to protect compressed air systems, pneumatic circuits, tanks, and pipelines from overpressure and excessive vacuum conditions. Control Devices valves are available with male NPT connections ranging from 1/4 in to 3 in, and preset or adjustable pressure and vacuum settings. For example, the SB75-0A150 soft-seat safety valve has a 3/4 in MNPT inlet, brass body, silicone seat, and is preset at 150 psi. The VR10-013 vacuum and pressure relief valve has a 1 in MNPT brass body and covers 0 in Hg to 13.3 psi pressure and 0 in Hg to 27 in Hg vacuum. Stainless steel options such as the VRGSS038-001 and VRGSS300-001 provide vacuum relief from 0 in Hg to 28 in Hg with 3/8 in and 3 in MNPT connections, respectively. 3G Electric supplies the Control Devices line to industrial buyers worldwide, including plant engineers, maintenance managers, and procurement specialists. The product range supports applications in compressed air systems, pneumatic controls, process piping, and tank protection. 3G Electric provides access to genuine Control Devices parts with published specifications, helping buyers match connection size, body material, seal material, and pressure or vacuum rating to their system requirements. The catalog includes both standard and specialized configurations, such as soft-seat safety valves for precise cracking pressure and stainless steel vacuum relief valves for corrosive or sanitary environments. Technical documentation and manufacturer part numbers are available to support specification and procurement. 3G Electric interprets demand for these components and sources them from established supply channels, offering a straightforward path to obtain Control Devices valves for maintenance, repair, and new installations. The focus is on delivering the specified part with the correct ratings and materials, without substituting unverified alternatives. For buyers who need to protect pneumatic equipment from overpressure or vacuum collapse, the Control Devices line provides a range of options with defined performance envelopes. 3G Electric's role is to make these parts accessible globally, with attention to part number accuracy and specification clarity. Whether the requirement is a 1/4 in brass vacuum relief valve or a 3 in stainless steel vacuum relief valve, the catalog covers common and less common sizes. 3G Electric does not manufacture these products; it distributes genuine Control Devices components and provides specification data to assist selection. The company's global shipping capability means buyers outside Singapore can obtain these parts without regional restrictions. For maintenance teams, having access to the correct relief valve can prevent equipment damage and unsafe conditions. 3G Electric aims to support that need by maintaining a catalog of Control Devices products with clear, verifiable specifications.

Guides & Resources

Frequently asked questions

Common questions about CONTROL DEVICES from 3G Electric.

What is the difference between the Control Devices VR series and VRG series vacuum and pressure relief valves?

The Control Devices VR series, such as the VR10-013, VR25-100, VR38-100, and VR75-100, features brass bodies and provides both pressure relief (0 in Hg to 13.3 psi or 14.7 psi) and vacuum relief (0 in Hg to 27 in Hg). The VRG series, including the VRGSS038-001, VRGSS300-001, and VRG150-001, offers vacuum relief from 0 in Hg to 28 in Hg and is available in stainless steel or brass. The VRG series typically has a slightly higher vacuum relief range and may be chosen for applications requiring stainless steel construction or a different vacuum setpoint.

What materials are used in Control Devices soft seat pneumatic safety valves?

Control Devices soft seat pneumatic safety valves, such as the SB75-0A150, are constructed with a brass body and a silicone seat. The silicone seat provides a soft seal that can improve sealing performance at lower cracking pressures. These valves are preset at a specific pressure, such as 150 psi, and are used to protect compressed air systems from overpressure. The brass body offers corrosion resistance in typical pneumatic environments. For higher corrosion resistance, stainless steel options are available in other Control Devices valve families.

What connection sizes are available for Control Devices vacuum relief valves?

Control Devices vacuum relief valves are available with male NPT connections ranging from 1/4 in to 3 in. For example, the VR25-100 has a 1/4 in MNPT connection, the VR38-100 and VRGSS038-001 have 3/8 in MNPT, the VR75-100 has 3/4 in MNPT, the VR10-013 has 1 in MNPT, the VRG150-001 has 1 1/2 in MNPT, and the VRGSS300-001 has 3 in MNPT. This range covers common pipe sizes in pneumatic and process systems. When selecting a valve, match the connection size to the system piping to ensure proper installation and flow capacity.

How do I select the correct Control Devices relief valve for my compressed air system?

To select a Control Devices relief valve, determine the required pressure and vacuum relief ranges, the connection size and type, and the body material compatibility with your system. For compressed air overpressure protection, a soft seat safety valve like the SB75-0A150 with a 150 psi preset may be suitable. For combined pressure and vacuum protection, the VR series offers ranges such as 0 in Hg to 14.7 psi and 0 in Hg to 27 in Hg. For vacuum-only protection, the VRG series provides up to 28 in Hg vacuum relief. Consider stainless steel bodies for corrosive environments. Always verify the valve's rated capacity meets or exceeds the system's relief requirements.

Are Control Devices valves suitable for vacuum service on tanks and pipelines?

Yes, Control Devices offers vacuum relief valves specifically designed to protect tanks and pipelines from excessive vacuum. The VRG series, including the VRGSS038-001, VRGSS300-001, and VRG150-001, provides vacuum relief from 0 in Hg to 28 in Hg. These valves are available in stainless steel and brass bodies with various MNPT connection sizes. They are used in pneumatic and process control systems to prevent vacuum collapse. The VR series also provides vacuum relief up to 27 in Hg in combination with pressure relief. Selection depends on the required vacuum setpoint, connection size, and material compatibility.

What is the pressure range of the Control Devices VR10-013 vacuum and pressure relief valve?

The Control Devices VR10-013 has a pressure relief range of 0 in Hg to 13.3 psi and a vacuum relief range of 0 in Hg to 27 in Hg. It features a brass body and a 1 in MNPT connection. This valve is used to protect pneumatic systems from overpressure or vacuum conditions. The pressure range indicates the maximum pressure at which the valve will relieve, while the vacuum range indicates the maximum vacuum. When specifying, ensure the system's operating pressure and vacuum levels fall within these ranges for proper protection.
