Medium Pressure Needle Valves

Medium Pressure Needle Valves

Parker Autoclave Medium Pressure Valves features include the largest-port valve available for medium pressure applications and a rising stem/barstock body design. Tubing size 1-1/2″. A non-rotating stem prevents stem/seat galling. The new one piece stem design permits ease of assembly and packing replacement. Metal-to-metal seating achieves bubble-tight shut-off, longer stem/seat life in abrasive flow, greater durability for repeated on/off cycles and excellent corrosion resistance. PTFE encapsulated packing provides dependable stem and body sealing. Stem sleeve and packing gland materials have been selected to achieve extended thread cycle life and reduced handle torque. There is a choice of Vee or Regulating stem tip. Available in two body patterns.autoclave-engineers-logo[1]

Micro Metering Valves

Micro Metering Valves

Parker Autoclave Engineer’s micro metering valves are designed for applications where more precise control of small flows is required than is possible with a standard regulating stem. Barrel and Thimble micrometer design permits settings to be repeated. Metering is effected by a finely tapered stem acting in a precisely mated replaceable seat. Very fine stem position is achieved utilizing a 40 TPI thread. The Barrel and Thimble are set for proper metering at the factory.autoclave-engineers-logo[1]

Diverter Valves

Diverter Valves

Parker Autoclave Engineers diverter valves provide the ability to direct incoming flow to one of two outlets. Flow is changed by rotating the handle in or out causing a double-ended stem to block the flow path to the outlet not needed. Diverter valves eliminate the need for multiple valves and the possibility of error in flow direction changes.autoclave-engineers-logo[1]

Extreme Temperature Valves

Extreme Temperature Valves

Parker Autoclave Engineers extreme temperature valves have come in two different styles of valves for extreme temperature. Standard valves can be supplied with packing for operation from -100°F (-73°C) to 800°F (427°C), or with the addition of an extended packing housing for operation from -423°F (-252°C) to 1200°F (649°C). The extended packing housing provides the means of removing the packing from the extreme temperature medium. Machined grooves on the housing act as a heatsink to remove heat or cold.The second, which is economically priced, is a modified standard designed for the power industry. It operates to 1200°F (649°C) with graphite packing and no extended packing housing.autoclave-engineers-logo[1]

Block and Bleed Needle Valves

Block and Bleed Needle Valves

Parker Autoclave Engineers series MVBB block and bleed valve is a two stem manifold valve providing an economical and convenient method of blocking, bleed-ing and calibrating pressure transmitters and gauges. The valve utilizes the mini valve packing and stem design making it compact and easy to use. The valve can be surface or panel mounted for safe operation. In addition, manifold style valves reduce the number of fittings and space required for installation.autoclave-engineers-logo[1]
