Valve bonnets are available in many designs and models (the most typical are: bolted, round bolted, welded, pressure seal) and are manufactured in cast steel or forged steel (generally using the same material grade of the body) Product line: Bolted bonnet high pressure valves (large forged) valves. Size range (s) NPS 2 1/2 - 14. (DN 65 - 350) Pressure rating. ASME Class 150 - 1500. Standard connections. Socket weld, Butt weld BONNET. It is machined in the same grade of the body or in superior alloys, if required. The pressure seal design keeps it tight to the body at high pressures even if bolts are loose or material dilatation occurs. It can be cast or machined from bar
Valve Bonnet. The cover for the opening in the valve body is the bonnet. In some designs, the body itself is split into two sections that bolt together. Like valve bodies, bonnets vary in design. Some bonnets function simply as valve covers, while others support valve internals and accessories such as the stem, disk, and actuator Valtek valves equipped with extended bonnets are designed to be installed vertically. This ensures a stag-nated, moderate temperature vapor barrier inside the bonnet, protecting the packing from the process. CAUTION: Do not insulate the extended bonnet or bonnet extension. Although thermal insulation may be installed on the valve body and adjoining pipin
Bolted Bonnet Gate Valves L&T Valves Valve Manufacturing Unit Larsen & Toubro Limited L&T Campus, Malumichampatti Coimbatore - 641050 Tamil Nadu India Website: www.lntvalves.co Fig. 1 depicts the typical Bolted Bonnet valve. The body flange and Bonnet flange are joined by studs and nuts, with a gasket of suitable design/material inserted between the flange faces to facilitate sealing. Studs/nuts/bolts are tightened to prescribed torques in a pattern defined by the manufacturer to affect optimal sealing. However, as system pressure increases, the potential for leakage through the body/Bonnet joint also increases

Cryogenic valve (below -50 deg Celcius) use the term of Extended Bonnet and High temperature valve (the threshold slightly differ between some standards) use the term of Heat Dissipation Bonnet. Special (expensive and not easy to fabricate) soft material capable to meet below (for cryogenic) and or above (for High temperature) of this threshold The Bonnet - Valve Body connection on globe valves comes in a variety of designs. Bonnets may be joined to the valve body by means of bolts, flanges, welding, or by means of a pressure-seal mechanism; or the bonnet may be an integral part of the valve body. Few of the bonnet - valve body connections are detailed out further Types of gate valve based on body, bonnet connection. 1st is screwed bonnet: This is the simplest design available and it is used for inexpensive valves. 2nd is bolted-bonnet: This is the most popular design and used in a large number of gate valves. This requires a gasket to seal the joint between the body and bonnet bonnet: The portion of the valve that contains the packing box and stem seal and may guide the stem. It may also provide the principal opening to the body cavity for assembly of internal parts or be an integral part of the valve body. It may also provide for the attachment of the actuator to the valve body . Threaded seat rings facilitate maintenance and/or replacement. On request, they can also be supplied as tack or seal welded.
