Maximize Efficiency with Sequence Valves: Direct Acting and CNC-Turned with External Pilot
What are poppet type 3-way valves?
A poppet type 3-way valve is a type of valve that has three ports and uses a poppet mechanism to control the flow of fluid or gas between the ports. Poppet valves are commonly used in hydraulic and pneumatic systems, where they are known for their reliability and durability.
In a poppet type 3-way valve, the poppet is a small cylindrical or cone-shaped piece that is located inside the valve body. When the valve is in its closed position, the poppet is pressed against a seat, which prevents fluid or gas from flowing through the valve. When the valve is opened, the poppet moves away from the seat, allowing fluid or gas to flow through the valve.
The three ports on a poppet type 3-way valve are typically labeled as the inlet port, outlet port, and exhaust port. When the valve is in its closed position, the inlet port is connected to the exhaust port, while the outlet port is blocked off by the poppet. When the valve is opened, the inlet port is connected to the outlet port, while the exhaust port is blocked off by the poppet.
Poppet type 3-way valves are commonly used in applications where it is necessary to control the direction of flow of fluid or gas, such as in hydraulic or pneumatic actuators. They are also used in applications where it is necessary to switch between two different fluid or gas sources, such as in chemical processing or oil and gas production.
What are 2 way and 3 way Sequence Valves?
A sequence valve can be either a 2-way or 3-way valve. A 2-way sequence valve is a type of hydraulic valve that is used to control the sequence of operations in a hydraulic system with two branches. It is designed to allow the flow of hydraulic fluid from one branch to another in a specific order.
In a 2-way sequence valve, the inlet port is connected to the primary circuit, and the outlet port is connected to the secondary circuit. The valve is set to open at a specific pressure, which is determined by an adjustment screw or a spring. When the pressure in the primary circuit reaches the set point, the valve opens and allows the hydraulic fluid to flow into the secondary circuit. This opens the downstream valve, and the secondary circuit starts to operate.
A 3-way sequence valve is a type of hydraulic valve that is used to control the sequence of operations in a hydraulic system with three branches. It is designed to allow the flow of hydraulic fluid from one branch to another in a specific order.
In a 3-way sequence valve, the inlet port is connected to the primary circuit, and there are two outlet ports, one connected to the secondary circuit and the other to the tank. The valve is set to open at a specific pressure, which is determined by an adjustment screw or a spring.
When the pressure in the primary circuit reaches the set point, the valve opens and allows the hydraulic fluid to flow into the secondary circuit. This opens the downstream valve, and the secondary circuit starts to operate. At the same time, the valve directs the excess hydraulic fluid to the tank through the second outlet port, preventing overpressure in the system.
Once the pressure in the primary circuit drops below the set point, the valve closes, preventing the backflow of hydraulic fluid from the secondary circuit to the primary circuit. This process ensures that the secondary circuit operates only after the primary circuit has reached a specific pressure level, thereby preventing damage to the system or the equipment.
