A pressure seal non-return valve is designed to allow unidirectional fluid flow while preventing backflow in high-pressure and high-temperature systems. Its pressure seal bonnet ensures a tight and reliable seal, becoming more effective as internal pressure increases, making it suitable for demanding industrial applications. The valve is available in two connection types: flange end and buttweld. The flange end version facilitates easy installation and maintenance, while the buttweld version provides a permanent, leak-tight connection for critical and long-term use. Commonly used in industries such as oil and gas, power generation, and petrochemicals, this valve is valued for its durability, efficiency, and ability to handle extreme operating conditions.
