Description

GATE VALVE HIGH TEMPERATURE / PRESSURE – PERSTA 700HJ / JJ

The PERSTA 700 HJ / JJ is our weldable gate valve (or flanges), DIN and ASME standard for high performance applications, thanks to its design and quality it resists high pressures and temperatures .

The valve body is made of one piece in die-forged steel, incorporating the bonnet and the guide for the closure, since the forged parts, compared to the cast steel parts, are generally free of porosities , cavities and weld seams .

Hardened seats (valve body and closing device) in order to provide them with extreme resistance to wear .

The valve has a bolted bonnet with reduced shaft screws to improve adaptability when temperature and pressure fluctuate.

The seats do not offer reduction of the step in the area except in the DN 65/50 and DN 125/10 designs.

Anti-return and anti-rising stem that offers minimal wear of the gland packing compared to ground surfaces of the stem.

The nominal pressure range is 10 to 300 bars. The maximum temperature is -10ºC to 550ºC . The seat of the body is welded with stellite.
