Description
The externally controlled straight-seat valve consists of a pneumatically actuated piston drive and a 2/2-way straight-seat valve housing. The drive is made from PA or PPS for special operating conditions. The reliable, self-adjusting gland ensures high tightness. These maintenance-free and robust valves can be retrofitted with a comprehensive range of accessories for position indication, lift limitation or manual operation.
