Oil, Natural gas, Water and Chemical Transmission Pipeline application, Metal to metal sealing ball valves can be used for rubbing, abrasive, corrosive and high temperature medium.
Oil, Natural gas, Water and Chemical Transmission Pipeline application, Metal to metal sealing ball valves can be used for rubbing, abrasive, corrosive and high temperature medium.
Slab gate valve (Through conduit gate valve) has been designed as per API6D standard, including soft sealing slab gate valve, metal to metal sealing slab gate valve and expanding slab gate valve. Slab gate valves are mainly used for oil& gas, water pipelines, the design has two floating seats,grease injection system and double block & bleed system.
Flanged ends cast steel gate valve are used to cut or conect the pipe mediua under nominal pressure from 150Lb to 2500Lb, temperature between -46 to 600C. In oil, gas, chemical industry, power plants and other conditions.
Swing check valves are designed as per API6D/ABS1868/DIN/GHOST/GB standards, with bolted bonnet and pressure sealing bonnets. These check valves are mainly used for Oil, Gas, water pipelines, and soft sealing check valve also can be used for Natural gas with zero leakage.
Metal to metal BALL VALVES
(Hard sealing ball valve, Metal sealing ball valves)
Metal to metal ball valves are designed with hard seat sealing, such as Stellite or Tungsten Carbide coating, these valves are used for abrasive medium, high impuirty content, mine, high temperature pipeline.
