P170 series angle seat valves NO/NC 1/2“ – 2”

The P170 series includes 2/2-way angle seat valves, pneumatically operated, designed for automation, heating, water, hot water, steam (up to 180°C), and aggressive or food-grade fluids. The series consists of three variants:

P170: Standard normally closed angle seat valve.
P171: Normally closed angle seat valve for high-pressure applications.
P172: Proportional angle seat valve for precise flow control.

All valves feature an AISI 316 stainless steel body and PTFE/FKM seals, providing corrosion resistance and longevity. The angle seat design ensures high flow capacity and minimizes water hammer. The rotatable pneumatic actuator (Ø70) is made of polyamide 66 with 30% glass fiber and allows flexible installation.
