There are usually two types of valves, soft seated or metal seated. Without going into any further details about metal seated, here is what you need to know all about soft seated shut off valves.
What is a Soft Seated Shut Off Valve?
Soft seated shutoff valves are usually made with a thermoplastic or rubber material like NBR, EPDM, Natural Rubber or Silicon, depending on the media passing through. The inner tube/sleeve material of a soft-seated shut off valve also differs because of temperatures that they will be able to withstand. They offer the users an accurate flow control and can be used to shut off or vary the pressure of the fluid flowing through the pipes.
A soft-seated shut off valve is generally recommended for fluids, pellets & granules, powders, aggregates, dust, sludge, compounds, and even food products. See more industrial areas and applications.
Why Choose Soft Seated Shut Off Valves?
If you are looking for a shut off valve, a soft-seated shut off valve is a better choice than another material or valve type. The reason for that is simple. It has the ability to make the highest level of seat leakage class possible, and their rubber seat folds into the shape of a lip every time to ensure full closure of the valve.
If your aim is to achieve a tight shut off, then soft-seated shut off valves are the best at achieving that.

How much Torque is needed to operate a Soft Seated Shut Off Valve?
The soft-seated shut off valves will need a lower amount of torque than metal-seated ball valves, which usually require a higher torque for functioning and have a bigger actuator model. Due to this reason, a soft seated shut off valve can save a lot of space and is also lighter in weight.
Applications and Varieties
In general applications, for transference of oil, gas and water, these valves are used in place of their metal alternatives. Soft-seated shut off valves provide an exceptional seating capability. They are also durable and can work excellently in terms of clean service application duration. Some manufacturers make a soft-seated shut off valve by using a soft material, while other valve makers use a metal seat ring in addition to the soft material in place if its seat insert for a 2-inch size or above. Even though there is aluminium, POM plastic or stainless steel incorporated with the body of soft seated shut off valves, it is categorized as soft seated due to the use of soft rubber material which is in contact with the product passing through the valve bore.
Soft Seated Shut Off Valves are Versatile
Soft seated shut off valves are innovative and designed to meet the demanding conditions of slurries and other challenging processing fluids, and are a part of any processing industry that will be difficult to surpass. A soft seated shut off valve can suit a huge range of users needs, and can be produced with customised end connections.
There are many satisfied users of soft seated shut off valves, some of which have previously used ball valves and much prefer the benefits and difference of the soft seated shut off valves with a rubber pinching sleeve.
