This quick tutorial will walk you through what essentially sets soft-seal gate valves apart from their hard-seal cousins so that your selection process becomes easier while being based on your project's specific needs.
A soft seal gate valve is a combination of metal sealings along with some resilient. A soft seal gate valve can easily assure complete air tightness when the valve is fully shut. Application normally at conditions of less-extreme pressures.
In the case of a soft-sealed gate valve, the seal between the gate and the valve seat is achieved by the flexibility of the non-metallic material. In the gate valve, there is a gate that moves in the vertical direction, thereby controlling the fluid flow. During this motion, its direction is perpendicular to the direction of fluid flow inside a valve.
By contrast, the hard seal gate valve thoroughly put into practice with a metal-to-metal seal. It has got a hard metal valve seat besides the hardest metals and materials. Hard seal valves find a more appropriate position in heavy industries like oil and gas, chemical processing, and high-pressure steam applications. Because of the metal construction, with higher pressure applied, hard seal needs higher force to seal.
Soft seal gate valves feature metal combined with some other nonmetal like rubber and PTFE on the seal while the hard seal gate valves do utilize metal seals against metals.
Hard seal gate valves have been designed for the severest of conditions, especially high temperatures and pressures. It finds its perfect application in industries related to petrochemicals, power plants, or any heavy-duty applications. Soft seal gate valves find their application for low-pressure needs where temperature and pressure are not high.
The hard seal gate valves are of high strength and resistant to wear due to the metal-to-metal sealing design. The soft seal gate valves are normally shorter-lived in critical environments. They face worn-out conditions and require frequent maintenance or replacement.
Application fields for soft seal gate valves usually include municipal waterworks, residential plumbing, and low-pressure industrial systems. Hard seal gate valves find application in high-pressure systems, chemical processing, the oil and gas industries, and steam systems.
The soft seal gate valve is not suitable for very high-temperature applications. The non-metallic material used for the seal of a soft seal gate valve will degrade or loses its sealing capability under high temperature. For high-temperature applications, one should go for a hard seal gate valve.
Generally speaking, soft seal gate valves will tend to be more affordable due to less expensive sealing material and less overall complexity in manufacturing processes. Hard seal gate valves will be more costly because of their generally more complicated design and the materials that must be used in the metal-to-metal seals of the valve.
Soft seal gate valve in the case of low-pressure fluids where an inexpensive alternative is suitable. While hard seal gate valves can go to all types of uses involved with high-pressure fluid, abrasive, or extreme temperatures.
Generally speaking, it is necessary to cooperate with serious manufacturers for there to be reliable industrial gate valves available. FLUIDO represents one of the leading high-quality gate valves suppliers, able to develop and produce soft seal gate valves as well as hard seal gate valves in accordance with leading industrial standards. With durability and performance, and a long service life, BS5163 Flanged Gate Valves they are developing rank among the best options for numerous industrial sectors.
While the soft seal gate valves can operate under moderate conditions and provide cost-effective sealing, the hard seal gate valves are designed to work in extreme conditions that call for high pressure, temperature tolerance, and resistance to wear. Therefore, any operating condition shall be taken into consideration: type of fluid, pressure, and temperature to make the right choice.
You can always rely on FLUIDO for high-performance and reliable gate valves. Rich experience, along with paying a lot of attention to quality, ensures that all valve solutions are at the highest standard to assure peak performance in every application.
