F7023 | 4”(DN100) PNEUMATIC EMERGENCY VALVE
The term ‘Emergency’ valve refers to the fact that it has a shear groove designed to break in the event of an accident/collision to the run off pipes preventing spillage of the cargo. Low pressure drop, compact body, internal air cylinder, sequenced operation durability and stringent quality control.
FEATURES AND BENEFITS :
● High quality die cast body and component materials to international standards are used for durability and performance.
● Lightweight aluminium construction for increased payloads – 4.85 kg.
● External shear groove meets TTMA and NTTC DOT 406 to limit product spillage in the event of an accident.
● Closure by self-centring plunger and durable compression spring.
● Removable bonnet assembly enables seal change without removing valve from the tank truck.
● Parts common to other valves in our range to minimise spares inventory.
● Flanges to TW 01 standard.
● Screen filter fitted as standard to prevent seal damage.
● Manual opening device for emergency discharge of cargo.
● Hydrodynamic body design minimises pressure drop to give high fl ow rate.
● Sequenced air cylinder provides positive open/closed indication.
● Viton seals are standard for compatibility with high-octane fuels and additives.
● Easy servicing allows the air cylinder piston assembly to be replaced without removing the valve from the tank pipework.
● 6 mm air connections.
APPROVALS:
● Shear groove meets TTMA and NTTC DOT 406
● CEN
● Flanges to TW01 Standard

F7043 | 4”(DN100) LOW PROFILE PNEUMATIC EMERGENCY VALVE
90 degree elbow body, the low body profile can help tank designers to lower centre of gravity, gain fifth wheel clearance and aid pipe-work orientation in tight spaces.
FEATURES AND BENEFITS :
● Low Profile Elbow Body.
● High quality die cast body and component materials to international standards are used for durability and performance.
● Lightweight aluminium construction for increased payloads – 6.5 kg.
● External shear groove meets TTMA and NTTC DOT 406 to limit product spillage in the event of an accident.
● Closure – pressure balanced to close against fl ow or remain closed until signalled to open by pneumatic control.
● Self-centring plunger and durable compression spring.
● Removable bonnet assembly enables easy seal change.
● Parts common to other valves in our range to minimise spares inventory.
● Sump Flange to TW standard – Square flange outlet.
● Screen filter fitted as standard to prevent seal damage.
● Manual opening device for discharge of cargo in the event of air supply failure.
● Hydrodynamic body design minimises pressure drop to give high flow rate.
● Sequenced air cylinder provides positive open/closed indication.
● Viton seals are standard for compatibility with high-octane fuels and additives.
● Easy servicing allows the air cylinder piston assembly to be replaced without removing the valve from the tank pipe-work.
