• Higher admissible working pressures
• Reinforcement of the stem and coupling ring
• Removal of the critical weld at the intermediate pipe and valve body (lower part)
• Intermediate pipe is connected via thread, weld now only has a sealing function

The new design allow us to offer the sliding gate valve in DN200 !

The DN200 mounted with the tandem diaphragm actuator 500 cm2 makes a compact design,
large actuating force and small weight.
