Bolted Body Construction
zaishis
As a standard, the valves are manufactured in Peco bolted body designs, where the joint between the body and the connector is bolted.
Double block and Blee
Peco trunnion Mounted Ball valves are designed for upstream sealing, So that the double block and bleed features are automatically built in. The feature enables on-line affirmation of proper seat sealing. Bellows Seal ValvesThe load generated by the line fluid on ball is absorbed by the trunnion bearings and is directly transmitted to the valve body. The valve stem is hence free from any bending load which leads to reduced stem friction torque and enhanced stem seal life. The seat ring are allowed to float in the flow axis against a fixed ball so that the line pressure assist in pressing the spring-loaded upstream and on the seats is relatively low, enhancing seat life.
Cavity Relief
The seat design has a built-in automatic cavity relief mechanism. In the event of excessive pressure build-up inside the cavity, the springs that keep the seats pressed to the ball are pressed back by the seat, allowing the release of excessive pressure. This eliminates the need for having external cavity relief assemblies.
Fire-safe design
AIL Trunnion Mounted Ball Valves are Valves are fire-safe by design in accordance with API 6FA - Specification for Fire Test for Valves (equivalent to ISO 10497) and API 607 - Fire Test for Soft Seated Quarter-Turn Valves.Reducing Valves AIL has successfully fire-tested the Valves have been supplied in large Quantities for crude/gas pipelines, and in petrochemical and allied industries where fire hazard is an important consideration.
Blowout-proof Stem
Peco Trunnion Mounted Ball Valves have a bottom-entry stem design, where the stem butts against a shoulder in the pressure, WATER POWER CONTROL VALVEthe tighter the seal. This design offers safety features superior to those of top entry stem designs where the line pressure works to break the stem seating. This feature also online replacement of the gland packing, in case of an emergency.
Stem Sealing - assured safety
A high integrity sealing system is provided on the stem for assured protection to the atmosphere.
