Product Scope

Drain Outlet Valves

These are specially designed for transformer pipelines to control Oil at an elevated temperature as well as for drainage of oil.Types of Valves used for such application are Gate Type, Globe Type, Ball Type, Butterfly Type. Various material grades such as Bronze, Stainless Steel, Carbon Steel are available in these range of valves. Also, there are separate series of such valves for severe weather conditions like C5M, C3 etc as well as for areas where weather condition are very cold dropping to sub-zero levels. There are various choices with end connections of valves. 

Product features:

  • Nominal diameter DN15 and DN 32
  • Nominal Pressure up to PN 6
  • Temperature range from -60℃ to +115℃
  • Flanges acc. to DIN,ANSI or JIS
  • Outlet with male thread and screwed cap

Flanged Gate Valves

Gate Valves are characterized by a sliding disc or gate which is moved by the actuator perpendicular to the direction of flow. There are many variations in seat, stem and bonnet design in gate valves. They are available in a wide assortment of sizes and weights.

Gate Valves are used primarily as stop valves, i.e., fully open or fully closed. They are not normally considered for throttling purpose. They are suited for high pressure and high temperature use with a wide variety of fluids. They are not usually used for the slurries, viscous fluids etc.

Gate Valves usually have a low pressure drop when fully open, provide a tight seal when fully closed, and are relatively free of contamination build up. Gate Valves are prone to vibration when in a partially open state and are also subject to seat and disc wear. Some large size gate valves are not recommended for steam services. Gate Valves have slow response characteristics and require large actuating forces.

Flanged Globe Valves

Globe Valve are all characterized by a closer member ,usually in discor plug form, which is moved by the actuator perpendicular to a ring shaped seat. The flow passes from the inlet port through these at to outlet port. The types differ mainly in the orientation of the seat to the direction of flow through the valve.

Globe Valves are used primarily for throttling purpose. They are widely used along with Gate Valve in power and process piping system. Globe Valves may be considered a general purpose flow control valves.

Globe Valves are generally faster to open and close then the Gate Valves . Their seating surface are less subject to wear and tear. High pressure drop makes them useful in controlling pressure.

Their high pressure drop may be undesirable in many piping system. In large size they require considerable power to operate, thus necessitating gearing, lever etc. Globe Valves are often heavier then other valves of same flow rating.

Flanged Ball Valves

Ball Valves are designed and manufactured to give maximum performance on recommended service at the lowest possible initial and upkeep cost. Such valve design permits inspection and repair of seats and seals without removing the valves body from the line. A full range of GG stainless steel-bodied ball valve are designed for process industry applications and for other high corrosive environments . The range features stainless steel , investment cast valvebodies.

Other construction features includes, PTFE packing rings in a deep stuffing box provide a dynamic seal, giving long-term protection against fugitive emission. Tight manufacturing tolerances reduce body cavity to a minimum, lessening the risk of product contamination problems. Not to mention, the use of PTFE stem seal packing, body seal, ball seal & integrated PTFE spring loaded bushing on the gland follower, guarantees low turning torque for manual operation .

Butterfly Valves

Butterfly valves consist of a rotating circular plate or a pair of hinged semicircular plates, attached to a transverse spindle and mounted inside a pipe in order to regulate or prevent flow. These Valves designed by us are with an ‘O’ Ring at the Seating surface making the valve zero leakage. Also, the valve has anti oil theft locking mechanism as well as has indication showing the valve position. Forged Steel Butterfly valves manufactured by us are best suited to eliminate any possibilities of porosities as well as superior valve finish.
