OUR EXPERTISE
Enhanced containment for a cleaner environment.
Prism manufactures a wide range of tank relief vents and accessories, all guaranteed to deliver the industry’s lowest leak rates, extremely accurate set points, and extended life expectance. At the heart of all Prism vents is our patented technology, the counter0force pressure suspended valve assembly.
Accumulated knowledge and experience by engineers in the venting industry has been applied to create the standards governed by API 2000 that all manufacturers and end-users must adhere to. Being a major contributor to the progression of the modern tank vent, Prism sits as a member of the API 2000 Task Force to assist in the forward growth and fair play in the industry with focus directed towards safety and stringent testing procedures.
Why Tank Vents?
A tank vent is a device relied upon to control the pressure or vacuum of the vapor space in atmospheric or low-pressure storage tanks. Normal inbreathing and outbreathing of large tanks are common due to a multitude of factors including, for example, liquid transfer effects and thermal expansion and contraction. Emergency venting because of fire is also a very real safety concern that requires attention on a case-by-case basis. Tank vents come in multiple designs, sizes, and configurations based on their intended purposes, as well as having the ability to be calibrated to operate within predetermined parameters.
Prism Tank Vents
Up to 10X leak rate reduction!
Our truly unique vapor recovery system. The heart of Prism’s vent line is in the air purge seal we call the Counter Force. The seal acts as a pressure suspended valve sealing assembly, affording the lowest leak rate in the industry, and improving set point accuracy. The Counter Force helps to extend the life of the relief valve due to its air cushioned ride, pressure suspended valve assembly. This translates into savings of product loss, blanketing gas losses, maintenance, and rebuild costs. The user-friendly design of our bolt in stainless steel seat allows for valve servicing performed in position.
