Gate Valve - Bolted Bonnet Oval Type - DIN | Valvosider

Valvosider Bolted Bonnet Oval Type DIN PN16 Gate Valve

The Valvosider Fig. 1190 is a metal-seated gate valve designed for flow isolation in steam networks, condensates, thermal oil, industrial water, gases, and general process fluids. It functions as an on/off valve; intermediate positioning is not recommended due to increased wear on seats and gate. The series covers PN16, DN50–DN1400, with face-to-face F5.

Construction

• Oval body, bolted bonnet
• Outside screw & yoke
• Rising stem, non-rising handwheel
• Flexible wedge
• Renewable seats
• Graphite packing with wiper rings
• Gasket from stainless reinforced graphite

FAQ

When to choose over bellow seal?
When standard sealing with graphite packing is acceptable. For stricter fugitive emissions control, choose a bellow seal version.

What does F5 mean practically?
Longer installation length than compact types, useful for replacing existing DIN valves with long pattern.

Can it be automated?
Yes, with torque control, stem travel, ISO 5210 interface, and limit switches.
