- Features
- It is highly corrosion resistant and is suitable for many chemicals
- Bidirectional flow
- 1-piece massive valve body is lightweight, rugged and is as corrosion resistant on the outside as it is on the inside to resist environmental attack
- Valve body endcap is sealed with PTFE diametrical seal locked in compression to eliminate cold flow
- Stud and nut design, standard material is Hastelloy® C276, designed to minimize valve body stress when adjustment is required
- Packing gland is live loaded with belleville washers, eliminating unnecessary adjustment and aids in reducing stem emissions
- Packing gland standard materials is Hastelloy® C276 and is guaranteed not to corrode in hostile environments
- Stem insert is Hastelloy® C276 encapsulated with either carbon graphite reinforced vinyl ester or E-Plus™ epoxy resin
- Graphite/PTFE radial bearing prevents stem side loading aiding in eliminating emissions and extending packing life
- Chevron PTFE packing provides positive stem sealing while maintaining low turning torque
- Graphite/PTFE stem thrust bearing maintains low turning torque
- Ball material is carbon graphite reinforced vinyl ester or E-Plus™ epoxy, ball OD is micro polished to provide longer seat life, FEP encapsulated Viton o-rings energize seats to ball and aid in bubble tight shut off at low pressures
- PTFE cavity filled seats minimize cavity around ball which could retain process media
- Standards/Approvals: ANSI/ASME B16.10, API 598, ISO 5211 Certified, MSS SP-72
- Applications: For hydrochloric acid, calcium chloride, ferric chloride, isopropyl alcohol, phosphoric acid, potassium chloride, sulphuric acid
