General features：
• Full jacketed design effectively maintains the temperature of the media
• High-pressure resistant jacket for supply of steam or cooling media up to 1.0 MPa (145 psi)
• Reinforced PTFE bearing and packing rings for superior performance
• Split construction of cap and seat holder simplifies maintenance
• Compact and light-weight design
• Machined ISO 5211 top mounting flange • Positive position indicator
• Blow-out proof shaft (DN 100/ NPS 4 and larger)
• Shaft seals positioned low on the shaft to avoid fluid from sticking, minimizing excessive torque and shaft torsion
• In addition to standard E-seat, various seats are available. Each seat option will allow a wide range of performance, suitable for many applications - PTFE / PFA copolymer: E-seat (standard) - PEEK seat (option) - Gratite seat (option) - Metaltite seat (option)
