China New Product Reducing Valve - SY Series Drain Valve – Convista Detail:
Nominal Diameter | 3/4 “~4” |
Nominal pressure | ANSI 150LB-4500LB |
Body type | Y pattern of 45-degree angle |
Body material | A105, F22, F91, F92, F316H |
Bonnet | standard, cooling structure |
Trim | integral stellate seat |
Packing | Flexible graphite with stainless steel wire |
Flow characteristics | quick opening |
Two kinds of actuators are optional | pneumatic diaphragm actuator (pneumatic multi-spring and single-spring diaphragm actuator are optional as well as top-mounted and side-mounted handwheels) or piston actuator. |
1)Y-pattern forged body, little flow resistance, high CV value.
2)Disc with throttle piece, effectively protecting the sealing surface, extend valve life.
3)Disc & seat sealing surface are treated by special processing for anti-cavitation, anti-erosion.
4)Two guide rings in disc ensure stem bear balanced force, flexible movement to avoid jammed phenomenon.
5)High-quality flexible graphite packing GARLOCK imported, good chemical property and flexibility, low friction, long service life.
6)Fast switching speed, generally 3-5 seconds, effectively protect the system security, greatly reduce the time of the sealing surface eroded by the media.
7)Bonnet heatsink, sufficient cooling to protect pneumatic actuators and solenoid valve not affected by the high temperature. Chamber gasket clip wire the high mesh flexible graphite pad, better sealing performance and reliability than the average flexible graphite.
Pneumatic steam drain valves area installed in the steam pipeline of thermal power plants, which can be divided in accordance with the mounting position as:
·Main steam line drain valves
·Hot reheat line drain valves
·Cold reheat line drain valves
·First stage, second stage, third stage, fourth stage, fifth stage and sixth stage extraction steam piping drain valves
