Vertical Check Valve:
The valve disc is pushed up and opened by the pressure of the medium flowing in the forward direction; when the medium flows backward or stops, the valve disc automatically closes under its own weight (or spring force).
It’s a lift-type check valve, where the valve disc moves up and down inside the valve body perpendicular to the plane of the valve seat. Therefore, it’s mostly used for vertically installed pipelines (with the medium flowing upward).

Swing Check Valve with Weight Lever：
1. Fully automatic — no external power or manual intervention needed.
2. Balances fluid dynamics and gravity mechanically.
3. Slow-close designs use two-stage closing (fast then slow) to reduce water hammer and protect piping.

Swing Check Valve with Weight Lever
Purpose: Automatic backflow prevention in pipelines to protect equipment.
Working principle:
Forward flow: Fluid pressure pushes the valve disk open, overcoming the weight/lever resistance
Flow stops/reverses: Without sufficient forward pressure, gravity acts on the weight, quickly closing the disk and blocking reverse flow

A 45-degree check valve is a special type of check valve, with its main feature being that the valve disc closes at a 45-degree angle instead of the traditional 90-degree vertical closure. Its main features include:
1. Lower flow resistance
2. Short closing stroke and quick response
3. Good sealing performance

A 45-degree check valve is a special type of check valve, with its main feature being that the valve disc closes at a 45-degree angle instead of the traditional 90-degree vertical closure. Its main features include:
1. Lower flow resistance
Since the valve disc opens at a smaller angle, the fluid changes direction more smoothly, which significantly reduces pressure loss compared to vertical lift check valves. This makes it better for piping systems that are sensitive to pressure drops.
2. Short closing stroke and quick response
The valve disc rotates only 45 degrees from fully open to fully closed, shortening the closing time. This effectively prevents backflow and reduces the occurrence of water hammer.
3. Good sealing performance
Because of the small closing angle, the valve disc exerts less impact on the sealing surface, which helps extend the life of the sealing components and maintain good tightness.
