Non-slam Check Valve

Product Introduction

‌Axial flow check valve‌is an efficient and reliable industrial valve. The design is inspired by the pursuit of ideal check valve performance, and aims to provide maximum reliability and minimum maintenance and operation costs in different applications. Its working principle is to control the opening and closing of the valve clack through the pressure difference between the inlet end and the outlet end of the valve. When the pressure at the inlet end is greater than the sum of the pressure at the outlet end and the spring force, the valve disc is opened; On the contrary, the valve clack is shutdown and remains closed‌.

Product Advantages

1. The axial flow check valve adopts a shock-absorbing design, which avoids direct impact between the valve clack and the valve body when the ordinary check valve is opened, then reducing vibration and noise.‌

2. The axial flow check valve has small fluid resistance and large flow rate. The internal flow channel is straight and the flow resistance is small. It can reduce the energy loss of the fluid and reduce the pipeline pressure. At the same time, the reasonable design of the flow channel makes the flow rate larger‌‌.

3. The axial flow check valve can respond and close quickly. The valve clack is light in weight, low in inertia, and closes quickly. It contacts the valve seat surface with very little impact force to keep the valve seat sealing surface in good condition and avoid damage.

4. Axial flow check valves mainly include stainless steel axial flow check valves, carbon steel axial flow check valves, and seismic check valves.

Axial flow check valves are widely used in the following areas:

• Long-distance oil and gas pipeline system‌: Prevent medium backflow and eliminate noise and vibration.

• Large ethylene plant‌: Control the counterflow of the medium to ensure the safe and effective operation of the equipment.

• ‌Pump discharge application‌: Protect rotating equipment from damage caused by fluid backflow.

• ‌Cooling water system‌: Prevent water hammer in cooling water systems such as ethylene and liquefied natural gas.

• ‌Waterworks and transmission systems‌: Control water flow to ensure water quality.

• ‌Compressor discharge of conveying pipeline‌: Prevent medium backflow .

Q1: What is the efficiency of axial flow check valve?

A1: Axial flow check valve adopts axial flow design, and the flow velocity of fluid is evenly distributed during the flow process, which reduces fluid resistance and energy consumption, and improves fluid control efficiency‌.

Q2: Is the axial check valve noisy?

A2: The axial flow check valve has low noise during operation, eliminating the noise and water hammer phenomenon in the valve pipeline, ensuring the safety of equipment and pipeline‌.

Q3: Are axial flow check valves safe?‌

A3:‌The inlet of axial flow check valve adopts double-sealing valve seat structure, which ensures that the valve can achieve zero leakage in the closed state, and improves the sealing and safety of the system‌.
