| Variant 702/73-103 | |
|---|---|
| Connection: | Flanged |
| Material: | Ductile Iron |
| DN: | DN50 - DN300 |
| PN: | PN10 |
Features
- Bi-directional, can be installed independent of the flow direction
- Full bore with no reduction of the flow
- Plane bottom prevents sediment from being accumulated
- No cavity in the body and thus no risk of clogging
- U-shaped one-piece NBR sealing between the body parts makes up for tolerances in coating and casting. It is reinforced with a steel insert to protect it from being damaged during operation.
- Stem and gate connection is secured with self-locking nuts
- Supports integrated in the body casting protect the gate from deflecting under pressure
- Body of ductile iron with 100-150 μm UV resistant polyester coating, RAL 5017. Optionally of acid-resistant stainless steel or duplex
-
Yokes of carbon steel with coating 100-150 μm of plascoat PPA 571 Aqua
- Gate, stem, bolts and nuts of acid-resistant stainless steel
- Washers under the bolts protect the coating
- Slim design and low weight
- Adjustable top packing gland enables sealing replacement without disassembly of the valve
- Approved according to the 97/23/CE European Pressure Equipment Directive
- Electric linear actuator for 24 VDC, enclosed to IP66 moving/IP69K resting
