G.C.A Weir Type Pneumatic Valve
- Made only of high-purity fluorine resin material and is designed to generate optimal performance in handling high-purity chemicals.
- Bonnet is screwed onto the body(all-in-one assembly to prevent valve deformation and improve airtightness.
- Bonnet Lock and fitting Nut Lock stabilize and prevent loosening of valve components adding additional safety
- Visually identifiable on and off, fully closed and open, and flow direction indicators for precise valve operation
