Understanding the Different Types of Safety Valves for Your System

That’s where safety valves step up, acting like silent sentinels to vent excess pressure and keep your steam or flow systems steady. Proconex, with 75+ years of hard-earned expertise, brings you top-shelf safety relief valves from leading brands like Emerson. Let’s break down what these valves do, why you can’t run without them, and how to pick the right valve types for your setup.

Think of a safety valve as a pressure watchdog. It’s a device that flips open to release extra pressure in things like boilers, pipelines, or reactors, stopping blowouts or breakdowns before they start. Unlike valves you turn by hand, pressure safety valves work solo, kicking in when pressure hits a set point and locking shut when things settle. In steam or flow systems, valve safety is your first line of defense. A piece in Valve Magazine says the right safety valves can cut overpressure mishaps by 40 percent.

You’ve got to match your types of safety relief valves to the job. Here’s the lineup:

• Spring-Loaded Safety Valves: These pop open fast for sudden pressure jumps; think boilers or oil rigs. Emerson’s Crosby valves shine here.
• Pilot-Operated Safety Valves: They use system pressure for tight control; great for refineries. Anderson Greenwood leads the pack.
• Balanced Bellows Valves: Handle weird backpressure shifts; perfect for chemical plants.
• Thermal Relief Valves: Tackle pressure from heat expansion; common in liquid lines.

Pumps & Systems notes spring-loaded valves cover 50 percent of industrial uses because they react in a snap. Proconex points you to the right one.

Picking a safety valve means knowing your system cold. Weigh these contributing factors:

• Pressure and Temp: Match the valve to your system’s max pressure and heat. Crosby valves take up to 3,000 psig.
• Fluid Type: Steam, gas, or liquid? Valve Magazine says pilot-operated valves rule for gases.
• Flow Rate: Get a valve that can handle your system’s flow without choking.
• Regulations: Stick to ASME Section VIII or API 526 to keep things legal.

A Control Global survey blames 45 percent of valve failures on bad sizing. Proconex’s team makes sure you get the sizes you need.

Proconex, the Mid-Atlantic’s Emerson Impact Partner, has 75+ years of safety valve street cred. We stock a deep bench of safety valves—Crosby, Anderson Greenwood, and beyond—for industries like:

• Chemical
• Oil and gas
• Power
