Low Pressure Needle Valves
Parker Autoclave Engineers valves are complemented by a complete line of low pressure fittings, tubing, check valves and line filters. The 10V and SW series use Autoclave’s SpeedBite connection. This single ferrule compression sleeve connection delivers fast, easy make-up and reliable bubble-tight performance in liquid or gas service.
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.
High Pressure Needle Valves
Parker Autoclave Engineers High Pressure Needle Valves are rated to pressures up to 30,000 psi (2068 bar), 40,000 psi (2760 bar), 43,000 psi (2965 bar), 60,000 psi (4137 bar) and 150,000 psi (10350 bar). Features including tubing sizes from 1/4” to 1”. The non-rotating stem prevents stem/seat galling and body design consists of a rising stem/barstock. For dependable stem and body sealing 30SC, 43SC and 30VM valves are furnished with PTFE encapsulated packing; the 40VM and 60VM valves feature nylon/leather packing below threads. Choice of Vee or Regulating stem tips.
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.
Parker Autoclave Engineers mini valves are complemented by a complete line of mini fittings and tubing. The MVE/MV Series uses Autoclave’s SpeedBite connection. This single-ferrule compression sleeve connection delivers fast, easy make-up and reliable bubble-tight performance in liquid or gas service.
The mini valves are available in five body patterns and with metric tube glands. The stem and packing gland design have been selected to achieve extended thread cycle life and reduced handle torque. Tubing sizes available are 1/16” and 1/8”.
Yoke Valves – Severe Service Valves
Parker Autoclave Engineers Yoke (Y Series) valves are rated to pressures up to 50,000 psi (3447 bar). These valves are extra heavy-duty, plant grade instrument valves for industrial and severe service applications. The valves feature low closing torque for ease of operation and are designed for use with Parker Autoclave Engineers medium and high pressure tubing and fittings.
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.
Parker Autoclave Engineer’s Needle Valves can be supplied with a number of options to meet your requirements. These include various materials of construction, packing material, high temperature packing, handle colors, stem options, custom valves, pneumatic actuators, and a number of other options.
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.
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.
