Safety Relief Valves

Safety Relief Valves for Industrial Systems

In a pressurized system, the safety relief valve (SRV) is the last safeguard against catastrophic failure. A Cross Company, we understand that a safety relief valve is a critical safety device that protects your facility from problems caused by blockage, thermal expansion, chemical reactions, and even external fire. And we also understand that “good enough” may not be good enough when it comes to personnel safety and asset protection.

Whether you’re managing steam boilers, complex pressurized systems, chemical processing lines, or anything in between, Cross can work with you to provide the certified overpressure protection your plant needs. We navigate the necessary codes and standards to ensure you get the exact valve required for your media, pressure range, and operating conditions.

Protecting Your Process from Overpressure

The main function of a safety relief valve is overpressure protection. They shouldn’t be used as a process valve or pressure regulator. Their job is to be the last line of defense as pressure builds within a process or system. That’s why it’s so vital they be constructed simply and consistently operational.

There are many common causes of overpressure incidents. Some of the leading causes include

  • Blocked discharge
  • Fire case (ie, process is exposed to an external fire source)
  • Unintended/unmonitored chemical reactions
  • Thermal expansion
  • Problems down the line (ie, heat exchanger malfunction, tube ruptures, etc)

Protect Your Process

Nothing can protect your facility from all accidents all the time. But you can have the right equipment in place to prevent the unsafe or risky conditions that cause these accidents in the first place. And the best first step to increasing safety is the right safety equipment. Protect your process, personnel, and equipment with Cross Company.

Did you know... A fingerprint weighs about 50 micrograms. We know, we weighed it! The residue left from a finger can actually make a difference in weight results which is why we wear gloves when we calibrate weights. For reference, a sheet of paper is about 4.5 grams, that’s 4.5 million micrograms.
Did you know… Cross Company has grown significantly since our start in 1954. Over the years we've acquired 26 companies! Today, our five groups have expertise in everything from industrial automation to precision measurement, and industry knowledge going all the way back to 1939.
