Standard construction of body- bonnet connections is bolted bonnet type. Welded bonnet is avaliable as alternative construction. Design of disc and hinge 

In addition, a swing check valve is easy to troubleshoot and easy to maintain with convenient top-entry access to all valve internals. In its standard configuration, these valves have a bolted cover and a free-swinging clapper. The clapper is the closing member that responds to the prevailing flow conditions. Design Standards*

Swing check valves are self actuating type.

The castings are precision machined for high performance of valve. Bolted Cover design

The traditional Swing Check Valve is defined in AWWA Standard C508, has metal or resilient seats, and swings through a 60 to 90 degree stroke. Because of the long stroke, inertia of the disc, and friction in the packing, the valve may slam in multiple‐pump and vertical‐pipe installations.

Swing Check Valves stud/nut will be ASTM A-193-B7M/A-194-2HM for standard temperatures (-20°F) (7) Optional drain plug is for valves 6” and larger.

A basic swing Check valve consists of a valve body, a bonnet, and a disk that is connected to a hinge. The disk swings away from the valve-seat to allow flow in the forward direction, and returns to valve-seat when upstream flow is stopped, to prevent backflow. The disc in a swing type Check valve is unguided as it fully opens or closes.

Swing check valves are a standard solution in a variety of industries. Power plants, gas transmission, and refineries frequently employ swing check valves. Swing check valves help

The Standard Specification for Public Building Works specifies that check valves attached to pumping pumps and air-conditioning pumps shall be "shock-absor type with bypass valves and if the total head exceeds 30m. Select springs suitable for the operating conditions. Use outside this range may cause vibration noise.

The basic swing Check valve consists of a valve body, a cover, and a disk that is linked to a hinge. The above disk swings, moving away from the valve-seat.

The standard covers inspection, supplementary examination, and pressure test requirements for both resilient-seated and metal-to-metal seated gate, globe, plug, ball, check, and butterfly valves. Pertains to inspection by the purchaser and to any supplementary examinations the purchaser may require at the valve manufacturer's plant. ANSI/API 599,
