SHANDONG SAIGAO GROUP CORPORATION

Saigao offers a full range of valves for drilling and production operations. Gate valves are designed and manufactured in accordance with API 6A latest edition PSL 1-4 while the robust, simple and reliable gate and seat design promotes ease of service with in-line maintenance.

Features include positive metal-to-metal sealing (gate-to-seat and seat-to-body), and stem packing that is chemically inert using spring energising rings which require no adjustment or plastic injection.

Stem packing can be replaced while the valve is under pressure and comes in API material classes AA through HH. Material for hydrogen sulfide and carbon dioxide service lies in accordance with NACE MR-01-175 latest edition. All valves are performance tested to PR2, with temperature ratings K through X up to 177°C (350°F).

Key Features of Valve

Key Features of Valve
  • Pressures up to 15,000 PSI for various API valve sizes

  • Metal-to-metal seals: Seals are stable, thermally insensitive and environmentally resistant; Utilised in the gate/seat, body/bonnet and stem/bonnet backseat

  • Selective backseat: Provides unparalleled safety during venting, lubrication and stem packing replacement; Allows stem packing replacement without removing valve from service

  • Slab gate: Assures smooth operation during extreme thermal cycles

  • Floating seats: Allows bi-directional use

  • Threaded packing gland: Transfers stem packing loads to the bonnet, protecting the bearing assemblies

  • No body penetration

  • Non-rising stem

  • Stem shear pin

  • In-line repairability


Valve Application

Today, people can find many types of valves in the market. Among them, the most typical manual valves will be the ones used in steam systems such as gate valve choke valve, check value and ball valve. 

Valves are now widely applied in petrochemical, chemical production, thermoelectric industry, natural gas pipeline, coal chemical metallurgy, environmental protection transformation, food and medicine, municipal water affairs and real estate construction.
