Usmani Valves Cryogenic valves are specially designed for gas treatment processes and storage and transportation of liquefied gasses such as LNG, liquid nitrogen, Oxygen,. Etc. These valves are required to be operated to give assured leakage rates. These valves which are recommended to use below -50 Deg C are designed with an extended bonnet which separates the operatorand stem seal from the cold temperature. 12” gas column is a standard feature for these valves. Extended bonnet

These valves are an extended bonnet with an enclosed vapor chamber to isolate packing from the cryogenic fluid and thereby allow packing to function properly.

Usmani Valves Cryogenic designs and liquid nitrogen testing facilities go much further to assure proven Performance in this most demanding application.

Materials:

• Suitable for working condition must be adopted for low temperature valves. Especially in the petrochemical industry, the types of fluids to be processed are different according to each section even in the same plants. At the same time, the temperatures used are also different. A full consideration must be paid to the selection of material.

Body and Bonnet:

• As for the materials constituting the low temperature valves, special consideration must be paid to the materials used at pressure parts as in the case of body and bonne

Specification:

Pressure Seal Class 900 Gate Valve supplied by Usmani Valves are mainly used in high temperature & high pressure applications such as power-plant steam service. The pressure sealed bonnet-body joint is a more positive way of sealing compared to its bolted bonnet counterparts because the internal pressure of the valve is used for bonnet sealing.

As the line pressure is elevated, the load between the sealing surface of bonnet and tapered gasket tends to be increased – the higher the line pressure (valve internal pressure), the greater the sealing force against the bonnet gasket. Hence a more effective sealing can be achieved. USMANI Valve’s pressure sealed gate valves are available in cast/forged carbon steel, alloy steel, or stainless steel materials furnished with end connections of butt welding (BW), socket welding(SW) and flanged(RF/RTJ). They are designed as per API 600 and ASME B16.34 covering pressure ratings of Class Class 900, Class 1500, Class 2500

Design Features:

• Flexible Wedge for improved seating and ease of operation,
  Especially in high temperature service.
  Wedges are accurately guided thru the entire stroke.
• Valves are full port design per ASME B16.34 Table A-1.
• Standard trim is stellite faced seat and disc seat surfaces, and
  13% chrome stem (API trim 5).Other trims available on request.
• Seat faces lapped for smooth finish and superior sealing.
• Stems are non-rotating with surface finish to maximize packing
  Seal for low fugitive emissions.
• Yoke arms designed for ease of gear, motor or cylinder actuator adaptation.
• Each valve is shell, seat and backseat pressure tested per industry standard API 598.
• Gland is two piece gland / gland flange design for optimal alignment and uniform packing compression.
• Each valve has a unique certification number that is traceable to the valve certification sheet which
  Includes MTR data, pressure test report, inspection report and certificate of conformance.
• Valve sizes 4” and smaller have bonnet take up ring design instead of support plate design.
• Weld end valves are B16.10 short pattern design. Flanged end valves are available on request and are B16.10 long-pattern design. Weld end valve dimensions given in table on next page.

Other available options as follows:

• Alternate valve materials such as chrome and stainless steel alloys
• Alternate trim materials -Bypass, drain and other auxiliary connections
• Gear, motor, and cylinder actuators available NACE service
• Special cleaning for applications such as oxygen or chlorine-Other options available as specified

Bolted Bonnet Valves - API 600

• Basic Design: API 600 & ANSI/ASME B 16.34
• Wall Thickness: ASME B 16.34
• Face-to-Face Dimensions: ANSI,ASME B16.10
• Flange End Dimensions: ANSI,ASME B16.5 (2” to 24”)
• Butt-Weld End Dimensions: ANSI,ASME 16.34
• Pressure, Temperature Rating ANSI,ASME B16.34
• Inspection & Testing: API 598

Specification:

Class 600 API 600/ BS 1414 Cast Steel Gate Valve are largely designed to start or stop a flow when a straight line flow of fluid and minimum flow restriction are needed. In service, these gate valves are pretty much kept either fully open, or fully closed. Gate valves are primarily made up to start or stop a flow when a straight line flow of fluid and minimum flow restriction is needed.

In service, these Gate Valves are pretty much kept either fully open, or fully closed. When turned open, the disc of the gate is completely removed allowing materials to pass. This gives the gate valve good shut-off property and allows it a bidirectional movement. They cannot be quickly blocked or unblocked. The Gate Valves shakes when it is blocked.

The gate valve is an OS&Y full bore with flexible wedge and rising stem. The body and the bonnet are made of castings and are connected by a flanged joint. The seating surfaces of the seats and the wedge are made in compliance with API 600. The seat rings are welded into the body. The gate valves are equipped with a back seat. The gate valves are a bi-directional sealing valves. The body-bonnet joint and the packing chamber are sealed with asbestos-free gasket and packing which guarantee a long life service. The requirement for an automatic body cavity pressure relief shall be specified in the purchase order. Pressure relief can be achieved by:

• Drilling a hole through one disc of the wedge,
• Special valve incorporated into the wedge,
• External bypass,
