BENEFITS
The 6C & 3C check valves can be configured to meet the needs of any system with the versatility in seals, crack pressures, materials and end fittings. By design, the product line also provides a streamlined flow path producing a low pressure drop. The seal options for these check valves are only limited by the compound availability. The product line is very competitively priced.
Snap-Tite S6C and 3C Series Check Valves (up to 6,000 psi) are soft seat, zero leakage poppet check valves with a two piece construction. The two piece construction allows for a variety of end fitting combinations.
Snap-Tite check valves have various standard crack pressures and flow rates up to 175 gpm. The S6C & 3C Series valves are available in a range of sizes and steel or stainless steel materials for flow capacities up to 175 gpm.
Snap-Tite Check valves are important components that are often overlooked when building a fluid system. A check valve can optimize system performance in the following ways:
- Ensure hydraulic fluid flows in only one direction
- Eliminate potential damage from back pressure
- Isolate sections of a system or system components
Basic check valve construction consists of a valve body with an inlet and an outlet port. Inside, a moveable poppet valve is controlled by spring pressure. In most cases the valve is normally closed, opening when the fluid pressure is greater than the spring force (crack pressure), thus allowing the fluid to flow in only one direction. When reverse flow attempts to enter though the outlet the poppet closes and flow through the valve is stopped.
Soft seat check valves have an O-ring or similar elastomeric seal between the poppet and body for improved leak resistance. The soft seat design is most compatible with ""clean” systems and is not indented for use in systems that have high surge flow. The seal material dictates the temperature range of the valve.
