Industrial Valves

High quality bellows sealed globe valve, with bellows made from AISI316Ti, INCONEL, HAST C-276. The bellows are welded onto the stem and hood, and also act as the joint gasket between body and bonnet. This type of stem packing is sublime which makes this valve suitable for steam and hot oil applications. Operating the hand-wheel ensures a calm opening of the valve, which prevents steam- and water-hammering in the pipes.

Spire specially adapted extended bonnet forged valves offer safe and efficient service including LNG liquefaction plants and receiving terminals as well as cargo systems of LNG and aerospace ground support facilities for liquid, hydrogen and oxygen.

All valves expect check valves are supplied with extended bonnet with a supplicant gas column length, usually specified by the user, to keep the stem seal packing exposed only to vapor and not the cold liquid to ensure functional integrity.

Pressure Rating: Up-to Class 2500#

Sizes: NPS 1/2” to 12” (DN15 to DN 300)

• Body and Bonnet: Austenitic stainless steel forgings used for bodies and bonnet after excellent impact strength, minimum heat loss and protection against corrosion. For cast steel valves radiographed castings are used only from specially approved foundries.

• Stem: To reduce galling, stem are made from advance Nitronic 50 with high tensile even at extreme low temperatures, excellent low friction and galling – free movement at points of stem contact. Alternative 316L stems are used for less demanding applications.

• Wetted Parts: All austenitic stainless steel. On small 1/4 - 2”forged valves, seat, wedges or discs are often Stellite 6.

• Yoke Bushing: Bronze or D2

• Packing: PTFE or other plastic packing protected from freezing by a column of insulating gas. For fire safe operation a secondary packing is provided using graphite.

• Seating Surface: Stellite 6 is used to prevent seizing and galling. When extremely tight shutoff is required, valves are supplied with CTFE, PTFE or other soft inserts.

• Bolting: Strain hardened Austenitic stainless steel.

• Cleaning: All cryogenic valves are thoroughly degreased, cleaned and sealed to prevent contamination

A double block and bleed valve is often used for a more positive isolation of a process fluid from other equipment. It normally consists of 2 block valves and a bleed valve, which apart from being hugely space saving can also save on time during installation and maintenance process.

When the process fluid is feeding the downstream equipment, the isolation valves 1 & 2 are opened and bleed valve 3 is closed.
When the downstream equipment is to be isolated from the process fluid, the isolation valves 1 & 2 are closed and bleed valve 3 is opened.
This is achieved by two Ball, Gate, Globe, Needle, etc valves placed back to back with a third "isolate" valve in the centre cavity.

Uses:

• In some automatic shutdown systems, to stop material flow, such as in fuel gas system for burners.
• to provide isolation of hazardous material, temperature or pressure during equipment maintenance or shutdown process.

Straight-through flow path minimizes pressure drop.
Blowout-proof stem and ball provides maximum safety.
Pressures to 20,000 PSI (1380 bar) at 22°C.
Pressure loaded seats assure positive sealing
Quarter-turn operation accommodates quick open and close needs

Through-conduit gate valves are isolating valves designed for full closing of the working media flow.

These gate valves are designed in compliance with API 6D and its application includes: Thermal Fluids, Polyethylene or Polypropylene,  Emergency Shutdown Valve, Coal conversion & gasification, Solids handling (powders, fines, dust and catalysts).

The advantages are no danger of entrapment of liquid in the body cavity, guarantee of 100% tightness, top entry design - possibility of refurbishment without removal from piping system, seating surfaces of the seats in permanent contact with the gate.

Specifically suited to handle food/chemical, gas production, corrosive, and water applications. This design is optimal for dangerous or corrosive liquid and gas, as any failure with the membrane will be kept contained by this bonnet. The raised lip/saddle design is best suited for small flow control and is kept leak-proof thanks to the bonnet over the diaphragm and actuator. Also, the sloped body makes this valve inherently self-draining.

Spire Industrial Equipments Co. globe valves are heavy duty, outside screw & yoke type, bolted bonnet, rising stem and hand wheel. Valves are highly efficient for services requiring frequent operation and throttling. The internal passage within the valve diverts flow through 90° changes of direction resulting in pressure drop and turbulence. The most advanced design features provides the ultimate in dependable, economic flow control. They are available in wide range of sizes and weights. Globe valves are generally considered where moderate control or regulation of flow is required.

Body : Body is cast with integral flanges meeting operating conditions with reinforcement to reduce stress. Flanged end and Butt weld end are available with ASME specifications.

Bonnet : Bonnet is as cast with integral yoke for better alignment and fewer parts. All bonnets are precision machines with exacting tolerance as the body for exact alignment of the stem and disc center.

Seat Ring : Renewable seat is hard faced and machined to minimize wear. The seat ring is seal welded to the body. Integral Seat is provided for Austenitic Stainless steel valves. High Quality deposits of Stellite 6 & other hard facing alloys are assured by use of controlled preheating and automatic plasma arc facing and controlled cooling process.

Globe Valves are adequate for all service media. Valves are marked with flow direction since they are recommended to install with flow and pressure under the disc. It can also be installed in reverse condition depending upon the conditions. The Globe Valve is generally faster to operate due to less travel. But requires much force to operate compared to Gate Valves.
