Description Material Performance Product Size Specifications

Product model: H76H
H76H double-lobe swing check valve for nominal pressure pn1.6mpa ~ 42.0mpa, Class150 ~ 2500LB; Nominal size DN15 ~ 1200mm, pns1/2 ~ 48"; Operating temperature: -196 ~ 540℃ on various pipelines, used to prevent media backflow. Valve body materials: carbon steel, stainless steel, can be used in water, steam, gas, oil, acid and other media.
Inlet double-lobe swing check valve H76H; H76W product introduction:
H76H double disc structure for double disc swing check valve with spring load disc, suspended on the center vertical pin shaft. When the valve opens, the resultant fluid action is at the center of the disc sealing surface, and the acting spring support force is at the center of the disc surface, causing the disc root to open first.
Inlet double-lobe swing check valve H76H; Working principle of H76W:
H76H double disc swing check disc is two semicircles with spring force return. The valve is usually closed due to the torque of the spring. When the fluid is flowing forward, the pressure of the fluid causes the disc to rotate around the hinge and the valve opens. Once the flow has stopped, the valve is closed before the flow can be reversed because of the spring.
Inlet double-lobe swing check valve H76H; H76W product features:
1, valve body structure length size small, good rigidity.
2. Safe and reliable performance and good anti-interference.
3, to achieve a complete seal, hydraulic test leakage is zero.
4, small size, light weight, compact structure, easy to maintain.
5, because of the role of speed closure, can prevent media backflow, eliminate water hammer effect.
6, easy to install, can be installed in the horizontal and vertical direction of the pipeline.
7, the valve plate using dual plate with two torsion spring design, can make the valve plate self-closing.
Scope of use: the product can be used in petroleum, chemical, food and other industries, due to the short structural length, generally applicable to the installation space is limited.
The product conforms to the standard: JB/T 8937.
