GZP Stainless Steel Swing Check Valve
Stainless Steel swing check valve is used mostly in the water flow systems. The check valves or tilt disc valves are useful for backflow prevention. ... The valves have a check disk inside them that allows the flow of water in a unidirectional flow.
One of the main advantages of stainless steel valves over valves manufactured of other types of metal is that they are extremely reliable and robust. Stainless steel 316 Instrumentation valves can be used at any temperature and do not have any issues when operating in very hot or exceptionally cold conditions
Stainless as a material is much more corrosion-resistant than brass. ... Stainless Steel Ball Valves will hold up much better to harsher water types. This will ensure a longer lasting valve. Remember that if you want to have more corrosion resistance built into your system, you should be using a full stainless system.
Swing check valves are available in either metal-to-metal seat or resilient seating. Resilient seated swing check valves are usually recommended for wastewater or services where dirt or other particles may be present in the fluid and positive shutoff is required.
Typically a swing check valve operation depends on gravity (weight of disc) and reverse flow. The pivot point of the swing check is outside the periphery of the disc and, the greater the flow velocity and head pressure possibility the greater the valve closing force. To prevent the slamming of the disc and reducing hydraulic shocks external hinge arm is available with either a lever weight or an adjustable spring.

Stainless steel check valves must be installed with the inlet in direction of arrow. This must be checked carefully before installing the valve. Placing a check valve in the opposite direction to the flow will prevent the disc from swinging free and will therefore prevent normal operation of valve.
Seat bores, minimum flows and pump coast down characteristics are crucial in check valve selection. Without proper sizing, extreme damage may occur in check valve internals. Pulsed flow reversals can also cause damage.

A valve is a device that regulates, guides, or manages the flowing of fluids (gases, oils, fluidized solids or slurries) by opening, closing, or partly hindering the different passageways. The valves are actually fittings but are generally referred to as different types. In an open valve, the fluid moves in a path from higher to lower pressure. In industrial settings, valves are widely used for a number of purposes. Valves are available in a variety of different types, but stainless steel valves have become more common for industrial applications. Let us discuss the advantages of the usage of stainless steel valves in commercial systems.
Advantages
Durability One of the main advantages of stainless steel valves over valves manufactured of other types of metal is that they are extremely reliable and robust. Stainless steel 316 Instrumentation valves can be used at any temperature and do not have any issues when operating in very hot or exceptionally cold conditions.
High-Pressure Resistance When you need valves that operate under high strain, stainless steel is the best way to go. Since SS is an extremely strong and durable product, the valves made of this material will withstand the pressure that would break or crack the valve made of plastic / PVC, brass, or bronze.
Free From Corrosion The components of metal which make up stainless steel are not prone to rust or corrosion. This makes the use of stainless steel valves the better option for industrial applications where the conditions may cause the metal to rust or corrode quickly.
Delivery time for goods: 15~30 days.
