High pressure straight through check valve

H42Y-320 High Pressure Direct Check Valve

A check valve with a high-pressure check valve disc sliding along the vertical centerline of the valve body. Internal threaded check valves can only be installed on horizontal pipelines. On high-pressure small diameter check valves, a ball can be used as the disc. The valve body shape of a butterfly check valve is the same as that of a globe valve (which can be used interchangeably with globe valves), so its fluid resistance coefficient is relatively large. The structure of a high-pressure check valve is similar to that of a globe valve, with the same valve body and disc as the globe valve. The upper part of the valve disc and the lower part of the valve cover are processed with guide sleeves. The guide sleeve of the valve disc can freely rise and fall within the guide sleeve of the valve disc. When the medium flows downstream, the valve disc opens by the thrust of the medium. When the medium stops flowing, the valve disc falls vertically on the valve seat, playing a role in preventing the reverse flow of the medium. The direction of the medium inlet and outlet channels of the through butterfly check valve is perpendicular to the direction of the valve seat channel; The vertical lifting check valve has a medium inlet and outlet channel direction that is the same as the valve seat channel direction, and its flow resistance is smaller than that of the straight through type.

H42Y-320 High Pressure Direct Check Valve

The valve disc of a high-pressure check valve is disc-shaped and rotates around the axis of the valve seat channel. Due to the streamlined channel inside the valve, the flow resistance is smaller than that of a butterfly check valve. It is suitable for large diameter applications with low flow rates and infrequent flow changes, but not suitable for pulsating flow. The sealing performance of high-pressure check valves is not as good as that of lift check valves. Butterfly check valves are divided into three types: single disc, double disc, and multi half disc. These three forms are mainly classified according to the valve diameter, in order to prevent hydraulic shock when the medium stops flowing or flows back.

A high-pressure check valve is a valve whose disc slides along the centerline of the valve body. Pipeline check valve is a new type of valve that has small volume, light weight, good processing technology, and is one of the development directions of check valves. But the fluid resistance coefficient is slightly higher than that of a swing check valve.

High pressure check valve is a valve used for cutting off boiler feedwater and steam, which has the comprehensive function of a lifting check valve and a globe or angle valve. In addition, there are also some check valves that are not suitable for pump outlet installation, such as bottom valves, spring type, Y-shaped check valves, etc.

A high-pressure check valve is a check valve in which the valve disc rotates around the pin axis inside the valve seat. The disc check valve has a simple structure and can only be installed on horizontal pipelines, with good sealing performance.

Structural characteristics of high-pressure direct check valve:

(1) The upper and lower valve bodies of H42H-160 and H42Y-320 high-pressure through check valves are connected by threads. Streamlined design with beautiful appearance

(2) H42H-160, H42Y-320 high-pressure through check valve disc and valve seat sealing surface are welded with Stellite alloy, which is high hardness, durable, and never wears out

(3) The internal structure of H42H-160 and H42Y-320 high-pressure through check valves is spring loaded through type. The valve has no noise during opening and closing, and the direction of fluid movement changes little, resulting in less pressure loss, reduced water hammer, and economic and energy-saving benefits. (Excellent structure)

(4) The manufacturing and acceptance conditions of H42H-160 and H42Y-320 high-pressure through check valves shall comply with the provisions of JB450. (Produced strictly according to standards)

(5) Can be installed directly or vertically (easy to install)

(6) Suitable for pipelines with a pressure of 10-40MPa. Reliable sealing performance and durability. It is an ideal product widely used in industries such as petroleum, hydropower, coal mining, and chemical industry.
