• The MC 307 Pressure Relief Vent is a stainless steel, pressure actuated unit that is engineered to limit excessive internal pressure to 130 percent of tank design.
• The standard model vent set at 25 PSIG will exhaust 26,700 SCFH at 32.5 PSIG and conforms to the emergency venting requirement code for MC 307 tanks having a total exposed surface area up to 700 square feet.
• The stainless steel valve seat is equipped with a replaceable Tef-O-Sil O-Ring.
• Provision is also made for a pressure gauge to be attached to the vent body.
• The entire vent is designed to be easily removed from the tank vehicle for inspection and cleaning
• An optional incorporation of a small vacuum section in the valve seat is also available upon request. It should be noted that this section, due to its limited size, may not be adequate enough to prohibit tank implosion.
