Karelin Control Valve

The next step in development of control and anti-surge equipment for pipeline transport.

We have created it with consideration for most demanding requirements in the industry sector.

Gazprom Organization Standard 2–4.1–212–2008:

7.4.2 Selection of type and nominal diameter of control valves shall be carried out in accordance with requirements to its maximum design flow capacity (Kv) (Cv in case of imported valves)
7.4.7 The design of the flow path of the valve provides a straight-line symmetric gas flow trajectory that maximally excludes sudden changes in direction (the principle of axial flow is preferred).

Specifications

Key characteristic of the gas pipeline valves is that their flow factor is 1.5 to 3 times higher than for analogous equipment of other manufacturers.

Energy loss reduction

Energy losses have been reduced by 5% owing to ideal axisymmetric design of the flow part, whereas energy losses for cage-guided valves exceed 60%.

The flow part heat-up

The world's first control valves with intrinsic heat-up function. This option is critical for equipment operating under low temperatures.

Reversal of flow

The only type of control valves featuring equivalent reversal of flow direction of gas, steam, or liquid. Characteristics of reversal flow remain the same.

Self-cleaning

The design minimizes damage to control valves by sand, welding burr, or other foreign inclusions. Repair interval is 2 times longer than for other types of control valves.

Repairability

Repair control valves without dismounting. Repair and mounting take several hours to several days. Equipment of other manufacturers is repaired up to half a year in factory conditions.
