Tank cover EHV

Emergency Pressure Vacuum Relief Valve is designed to provide emergency relief capacity beyond the normal operating pressure/vacuum relief valve on the tank. The valve protects the tank against rupture or excessive internal pressures caused by fire exposure, etc. The valve is designed to be self-closing. As excessive pressure builds up, it relieves, then reseats when over pressure has been dissipated. Benefits A wide stainless steel seat and air-cushion seal keeps leakage low long after the valve is put in service A hinged design including a lift stop ensuring positive re-seating for reliable performance Easy access manway combined with emergency relief
