Signs that Your Industrial Valves Need Repairs

Signs that Your Industrial Valves Need Repairs

Valves and pumps make up the life-blood (or rather arteries) of all of your industrial process, and as such, need to be able to serve you consistently. When downtime occurs due to a failed valve, the results can be costly, causing delays that your business could otherwise have done without. So to help you avoid such a mishap, here are some tips on how to spot your need for valve and pump repairs before they stop your processes in their tracks.

Internal Leakages

To know whether or not internal leaks are a sign of a faulty valve, you need to first know specified maximum allowable leakage for the valve concerned. All valves allow for a certain amount of internal leakage, known as the valve’s MAL. If internal leaks are going above this amount, it could point to worn components or poor configuration of the control system.

External Leakages

Externa leaks are never a good sign, especially where dangerous fluids are concerned, and this generally points to a problem with valve packing from improper maintenance, too much packing, damage from valve assembly vibrations and problems with thermal cycling.

No Ease of Movement

When issues occur with valves it is common for people to use more valve packing in them, this in turn, may prevent the valve from moving smoothly when it is operated. A stuck valve also often points to a problem with the positioner, particularly on pneumatic valves.

How a Mechanical Seal Works

How a Mechanical Seal Works

Mechanical seals are the solution to older mechanical seal problems. Preventing pumped fluid from leaking into the environment needed to be achieved so industrial working spaces were less hazardous in terms of safety. Increasingly strict environmental standards and harsher operating conditions have made pump sealing technology an active area of research. As industrial advancement brought… Continue Reading

Gland Packing

Gland Packing

A gland is a type of stuffing box sealant that is used to seal a rotating shaft against a fluid. The most common is the head of a tap called the faucet where the gland is usually packed with string which has been soaked in similar grease. The gland nut allows the packing material to… Continue Reading

What are Mechanical Seals?

A mechanical seal is a method of containing fluid in a vessel such as pumps, mixers, etc. The rotating shaft continues through a stationary point or occasionally, where the point rotates around the shaft. There are several mechanical seal types, like a pusher, conventional, non-pusher, unbalanced, balance and cartridge types. Below are some of the… Continue Reading
