TVD

The TVD is a thermal safety shut-off device that stops the gas flow in case of excessive ambient temperature, e.g., due to fire.

The valve is rated to shut the gas flow for 90 minutes with temperature up to 800 °C.

There are two sizes depending on the flow rate and required pressure drop: TVD1 and TVD2.

• Material: steel body
• Design pressure: up to 145 psig | 1 MPa
• Operating temperature: from -40 to +149°F | from -40 to +65°C
• Maximum flow rate: 1,500 scfh | 42.8 m³/h for TVD1, 3,500 scfh | 100 m³/h for TVD2
