Uni Klinger High Pressure Valve

UKL High Pressure Gate and Globe Valves are manufactured to the latest International designs, using latest, State of the Art technology and a strict quality control system. These valves are exceptionally Sturdy, Rugged and Durable. They are designed for a tight Seal, ease of operation with inbuilt Quality and Integrity for a long service life

UKL High Pressure Valves are manufactured in Gate as well as Globe valve types.

Gate valves - probably the most common valves in use today, esp. where an uninterrupted flow is required, because the gate fully retracts into the bonnet, creating a minimal pressure drop, when the valve is in an open position. Gate valves are specifically intended for use in isolation applications.
Globe valves the main advantage is that a globe valve opens more rapidly than a gate valve as the disc only needs to move a small distance from its seat to allow full flow. This is an advantage when there is frequent operation of the valve. The disadvantage is that the fluid has to change course, increasing the resistance to flow and generating turbulence. This results in a higher pressure drop across a globe valve than a gate valve. Globe valves are designed to close off, open up or throttle the flow in a pipeline.

Another very effective type of Bonnet construction, apart from the standard Bolted Bonnet type in a gate/Globe valve is the Pressure Seal Bonnet. This construction is adopted for valves for high to very high pressure service. The unique feature about the pressure seal bonnet is that the Body - Bonnet joints seal improves as the internal pressure in the valve increases, compared to other constructions where the increase in internal pressure tends to create leaks in the body-bonnet joint.

Uni Klinger Bellow Seal Valves

It has been proven through various studies about process plant emission that 75% of leakages are occurring through valves in pipelines.
The leakages cause
  • 1) Environmental pollution
  • 2) Production loss
  • 3) Process problems
  • 4) Energy loss.
    • In line with present emphasis on prevention of environmental pollution and energy saving, it is necessary to plug these leakages.
      Irrespective of proper selection, installation and periodic and preventive cares on conventional valves, leakages cannot be totally eliminated. Though performance seems to be satisfactory initially, they are bound to leak through gland after some operations. Selection of Bellow Sealed Valves is the only solution for this problem. Therefore, use of bellow seal valve is on the increase.

Bellow Seal Valves because they Aid, help and complement-

  • - Stringent fugitive emission Laws
  • - Environment Protection Laws
  • - Air Purification or Clean Air Act.
  • - Greenhouse Effect Prevention Bill
  • - Energy conservation Law
Available in Gate / Globe / Angle valves versions. They incorporate a Metallic SS bellows which is flexible welded to the shaft at the lower end and to the Body-Bonnet Flange at the other thus effectively shutting off any leak/emission to the atmosphere.
The Hydra Brand Bellows incorporated in UKL valves are imported from Germany, manufactured as per International Standards, ensuring a consistent and reliable performance, long life and uncompromising Quality.

Uni Klinger Piston Valves

UKL Piston Valve is basically Seat less and Glandless valve and by virtue of its design can replace both, the conventional type of Gate and Globe valves, with distinct advantages over them. The Klinger Piston valve works on the principle of resilient rings in conjunction with a Metallic Stainless Steel Piston that moves vertically between the rings, giving a Seal that is both effective as well as durable.

UKL piston valves are ideally recommended for critical and hazardous media, including Steam, Heat Transfer Oils, Acids, Gases, VACUUM.

Manufactured in Forged Carbon Steel / Stainless Steels to 800# - Sizes 15mm to 40mm, in SW and Threaded Ends. Cast Carbon Steel / Stainless Steels with Flanges to 150#, #300 & DIN standards 50 to 200mm.

Salient Features:

  • Economic, easy to service

UKL Piston valves can be provided with additional feature like:
  • Regulating Piston/Lantern Bush; for coarse regulating/Throttling operation
  • Extended Spindle: For Cryogenic application/Hot media to prevent heat transfer to H/W and aid handling of valve
  • Heating Jacket: For Media that tends to solidify/crystallize at low temperature and needs constant heating by either steam/Thermic oils circulated through the Jacket.
  • Pneumatic, Hydraulic or Electrical Actuator: For remote operating of the Valves
Inverted Bucket TRAPS

Steam used for secondary heating like Coils, vessels, heat exchangers etc, generate a lot of condensate post heat transfer. This large quantity condensate can handle by the Inverted Bucket Trap.This condensate has a substantial heat component with cost tagged to it. Also this is treated and pure water and can be used as Feed water for the Boiler, saving the cost of heating, Water Bill and Treatment chemicals.

Therefore it makes sense to recycle / reuse this condensate. This function is also done by the Inverted Bucket Trap, which works on the principle of Buoyancy, [densities difference of Water and Steam].The rising in condensate level fills and envelopes the Bucket causing it to sink which open the mechanically linked valve and discharges the condensate, and reverse, when the level of condensate drops Steam enters the bucket, causes the flotation of the Bucket which close the valve and stops condensate discharge & traps the steam.

  • MOC: CF8M
  • Available in Sizes: 15 mm - 25 mm
  • End connections: Universal connection to be mounted on ITVS

Ball Float Traps

Steam used for secondary heating like Coils, vessels, heat exchangers etc, generate a lot of condensate post heat transfer. This large quantity of condensate can handle by Ball Float Trap. This condensate has a substantial heat component with cost tagged to it. Also this is treated and pure water and can be used as Feed water for the Boiler, saving the cost of heating, Water Bill and Treatment chemicals. Therefore it makes sense to recycle / reuse this condensate. This function is also done by the Ball Float Trap.

UKL Ball Float Trap discharge condensate near to steam saturation temperature, which works on the principle of Buoyancy, [densities difference of Water and Steam].The rising condensate level elevates the Float open the valve and discharges the condensate, and reverse, when the level of condensate drops, valve close the trap. The working principle of this trap can also be used as Auto Air Moisture Drain, as Air Eliminator in liquid line, as well as for lifting condensate, as a pump.

Thermodynamic Steam Traps

Steam has two components:
1] the latent heat useful in process for Heat transfer, and
2] the Sensible heat in the form of condensate having only the heat content not useful in process, rather hindering Heat transfer and causing damage to piping equipment due to its presence. Hence, there is need to remove condensate and trapped steam. This is done by Steam trap.
The Thermodynamic Trap works on the principle of difference in the velocities of Steam and Condensate. Used Mainly on Drip lines of the main stream distribution line, uses condensate pressure to open the trap and discharge the condensate and then the Flash steam formed due to the high flash steam velocity & accumulation of flash steam over disc, Device close and trap the live steam when it appears.
Thermodynamic Steam Trap is compact and lightweight and discharge condensate as and when it is formed.

  • Max. Operating temperature: 425 Deg. C[UTD55] 550 Deg. C. [UTD62/120]

Thermostatic Steam Traps

This trap works on the difference in Enthalpy of Steam and Condensate. A capsule attached to a Bellow filled with precise amount of a Hydrocarbon, Expands and contracts in response to the rising/lowering of Enthalpy. Thereby shutting and opening the valve. Condensate has lower Enthalpy, causing the bellow to contract and the seat to retract which opens the valve and allow discharge of condensate. The reverse happens with the steam and its higher Enthalpy.

These traps used largely on tracing lines or Tank Farms where steam is supplied to maintain Temp / viscosity of the Oil. UKL Thermostatic trap has a unique Simple design, Minimum number of components and where the Bellow is enclosed and protected thus ensuring long life for the Bellows
