The valve fire test is a test that simulates a valve in an actual fire environment, which can reflect the fire resistance of the valve.

Movement mode: The gate of the handwheel thread gate valve moves linearly with the valve stem, also known as the opening gate valve.

The globe valve has the following advantages: simple structure, convenient manufacturing and maintenance. Short working hours and short opening and closing times. The sealing performance is good.

How to protect valves products?Ball valve, globe valve and gate valve should be applied with handwheel when opening and closing. Do not use levers or other tools to avoid damage to the valve.

The check valve can be used to supply a line in which the pressure may rise to an auxiliary system that exceeds the system pressure.

1. Straight-through globe valve: It relies on the stem pressure to tightly bond the disc sealing surface to the seat sealing surface to prevent media circulation.

The gate valve is a shutter of the opening and closing member, and the direction of movement of the gate is perpendicular to the direction of the fluid.

The Onero trunnion mounted ball valve is designed according to the API6D standard and is available in two-piece and three-piece split designs. The valve can be used over a wide range of pressures and temperatures (150 LB ~ 2500 LB and -46 ~ 200 ° C).

The opening and closing part of the forged steel gate valve is the ram. The direction of movement of the ram is perpendicular to the direction of the fluid.

1. Swing-type check valve: The valve flap of the swing-type check valve is in the shape of a disk, and rotates around the rotating shaft of the valve seat passage.

The ball of the ball valve is floating. Under the action of the medium pressure, the ball can generate a certain displacement and press on the sealing surface at the outlet end to ensure the sealing of the outlet end.

When the gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the shutter is pressed against the valve seat of the other side only by the medium pressure to ensure the sealing of the sealing surface, which is self-sealing.

Onero trunnion mounted ball valves are designed according to API6D standard and be offered two-piece and three-piece split body designs.
