For over 85 years Protectoseal has been an industry pioneer and leading manufacturer of quality products that conserve and control volatile emissions and protect low pressure storage tanks, vessels and processes from fire and explosion.
Our integrated line of pressure and vacuum relief vents, flame/detonation arresters and related vapor control devices are used primarily in process industries. For a full list of industries, click here.
PRESSURE AND VACUUM RELIEF VENTS
Vents that are specifically designed to prevent storage tank damage by relieving internal pressure and vacuum accumulations that occur as a result of day-to-day operations (filling, emptying and atmospheric temperature changes). These products also minimize product evaporation losses.
EMERGENCY PRESSURE RELIEF VENTS
Emergency Vents are designed to prevent the catastrophic rupture of a storage tank by relieving the internal pressure accumulation caused by external fire involvement of the tank.
500 PPM PRESSURE RELIEF VENTS
PIN-TECH® Pressure Vents are designed and tested to address concerns about the leakage of fugitive emissions prior to set point.
FLAME AND DETONATION ARRESTERS
Flame and Detonation Arresters provide a positive barrier against the propagation of a flame through a piping system or into a storage tank’s vapor space.
CE MARKED FLAME ARRESTERS
Flame and Detonation Arresters that conform to European Standard EN12874 and ISO16852.
TANK BLANKETING VALVES
Blanketing Valves sense the pressure in a tank’s vapor space and regulate a supply of pressurized inert gas into the tank so that a desired pressure range may be consistently maintained.
LIQUID LEVEL INDICATORS
Liquid Level Indicators are used for accurate liquid level gauging of fixed or floating roof storage tanks. Suitable for water, oils, solvents and other products.
SPECIALTY TANK VENTS & FITTINGS
Miscellaneous equipment required for the safe and efficient operation of storage tanks and related processing facilities. Products include: Air Dryers, Gauge Hatches, Internal Safety Valves, Overflow Valves, Water Drain Valves and more.
FUEL TANK SAFETY CAPS
Combination safety fill cap, flash arrester and pressure / vacuum relief device designed for installation in fuel tank openings of gasoline or diesel-powered equipment.
SAFETY SHUT-OFF VALVES
Heat actuated safety shut-off valve is specifically designed for installation in the withdrawal lines of flammable or combustible liquid storage tanks.
