The Vanaz V7744 is a spring-loaded safety relief valve that stays closed during normal operation and automatically opens to vent gas once line pressure rises to the preset limit, closing again once pressure drops back below the set point. Fitted with a soft seat, it is rated for a wide 5-120 kg/cm2 set-pressure range and is suitable for natural gas, LPG, CO2, nitrogen and argon service, protecting pressure-reducing systems, gas trains and pipelines from overpressure. Available with 1/2-inch, 3/4-inch or 1-inch BSP internal end connections as per requirement. Manufactured by Vanaz Engineers Ltd, Pune.
