protectoseal

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.

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.

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.

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.


AIR DRYER – SERIES 782
The Protectoseal No. 782 Air Dryer provides a simple, relatively inexpensive means of extracting unwanted moisture from make up air entering a storage tank.


FLASH ARRESTER FILL UNITS – SERIES NOS. 120/150
The Protectoseal Series No. 120 and No. 150 units, when installed in storage tank fill openings, protect tank contents from external ignition sources during filling operations.


FLAME ARRESTER RODDING & SAMPLING UNIT – SERIES NO. 400
Protectoseal Series No. 400 Units install in storage tank rodding and sampling openings and protect tank contents from fire during rodding and sampling operations.


FLASH ARRESTER FILL UNIT – SERIES NO. 500
The Protectoseal Series No. 500 Flash Arrester Fill Units are particularly suited for installation in storage tank openings where tanks are filled by direct connection from trucks or railroad tank cars.


GAUGE HATCHES – SERIES NOS. 4960D / 4970D / 4980D / 5960D
The Protectoseal Series No. 4970D and 4980D Gauge Hatches provide ready access to storage tanks for gauging or sampling.


INTERNAL SAFETY VALVE – SERIES NO. 3000
The Protectoseal Series No. 3000 Internal Safety Valves are intended for use on storage tanks containing flammable or combustible liquids. Safe and efficient, the valves help protect the tanks and their contents and provide valuable aid in accident prevention.


OVERFLOW VALVE – SERIES NO. 7300D
The Protectoseal Series No. 7300D Overflow Valve eliminates an open overfill pipe connection into the vapor space of the tank.


WATER DRAIN VALVE – SERIES NO. 660
Protectoseal Series No. 660 Water Drain Valves are designed to provide maximum flow and assure complete draining when relieving tanks of bottom water accumulated during normal breathing.


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.
