Kelite Group forged double block and bleed are available vor Modular DBB valve，Integral DBB valve，Single Block and Bleed valve ,3 piece trunnion ball valves, has been engineered to robust requirements.

Floating ball valve is a ball valve with an unsupported control device ,other than the 2 seats it rests on, so that the ball goes in the valve space to help seal off the line pressure. The key to floating ball valve performance is the design of seal, regardless of whether the seats are produced of plastic, metal and other stuff. Another vital feature of ball valve performance is the stem seal design. A typical floating ball control device seals off the line force using soft such as PTEE (a plastic matertial known as polytetrafluoroethylene and otherwise called as Teflon) or TFM. TFM has a slight temperature/pressure benefit over PTFE. Both known for the quite high temperature and pressure capabilities, PTFE and TFM are perfect options for seat material.

Fully Ball valves featuring with completely forged welded body perfect for applications of gas storage and transmission. The completely welded body design has no bolted bonnet or body joint leak for atmosphere issue.  Also forged steel body promises uniform perfect grain formation and hardiness free from inevitable cast control devices defects such as gas hole, porosity.

The initial benefit of metal seated ball valves is the capability to withstand high temperature and extreme service situations. Metal seated ball valve can endure severe flashing, abrasive process fluid, hydraulic shock, and high temperatures up to and exceeding 1,000 F. They are also perfect for high corrosion or erosion applications. Metal seat ball valve can be hardened by coating like ultrasonic spray coating, chromium carbide, satellite hard facing and tungsten carbide.

Top entry ball valves are designed for process isolation applications in the gas and oil, petrochemical industries and oil processing. A spec of top entry ball valve is the permit the valve interiors to be accessed by eliminating the top cover flange so that the internals can be serviced and removed. Another spec of the top entry ball is they are designed for hydrocarbon service and therefore be traditional to fire safe testing standards such as API 6FA/API 607. Advantages of top entry ball valve

• Superior bearing support of the blow-out proof stem make sure right zero seat leakage and axial alignment even on actuated valves.
• This highly-engineered carbide  chrome coating structure has best bond power and coating density to offer leak-free and  long-life performance even in top temperature-drop applications.
• An ISO-5211 integral mounting pad error-free facilities, motor, air and gear operator actuation due to best rigidity, precise alignment and a completely guided stem bearing system.
• In extreme atmosphere, the simpler the design and the fewer the parts, the excellent. The durable one-piece stainless steel helps to the longevity of the control device.

Trunnion ball valves are quarter-turn valves used to begin or stop the flow of a media in a pipe.It has a “free floating” design, so the trunnion type is a design change. Within a valve the ball links to the stem on single end and on the other end a shaft known as the trunnion. Due to this design change, the ball is strongly place. Trunnion ball valves are very versatile. They are used in lots of different kinds of industries because of their customizable specs.  For example, Trunnion ball valve specs O-rings and fire-safe stem packaging that stop leakages. It also comes with stainless steel sealant injection fittings for seat sealing or emergency stem. They are largely used in oil, petrochemical, chemical and gas, LNG and hydrocarbon industries. These valves are perfect for big scale high presure applications and compact, low-temperature conditions.
