Specifications

	Valve Size		Valve size is the designated size of the valve by manufacturer.  This typically represents the size of the passage opening.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Pressure Rating		Maximum safe pressure value for which the valve is rated.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Media Temperature		Maximum temperature of media the valve is designed to accommodate.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Connection
	Your choices are...
	Threaded		The valve has internal or external threads for inlet or outlet connection(s).
	Compression Fitting		A sealed pipe connection without soldering or threading. As the nut on one fitting is tightened, it compresses a washer around the second pipe, forming a watertight closure.
	Bolt Flange		The valve has a bolt flange(s) for inlet or outlet connection.
	Clamp Flange		The valve has a clamp flange(s) for inlet or outlet connection.
	Union		The valve has a union connection for inlet or outlet connection(s).
	Tube Fitting		The valve has a connection for directly joining tubing at the inlet and/or outlet connections.
	Butt Weld		The valve has a butt weld sized connection for inlet or outlet connection.
	Socket Weld / Solder		The valve has a socket weld connection for inlet or outlet connection.

Type of Control

	Actuation
	Your choices are...
	Manual / Hand		The valve is actuated (opened or closed) via a hand operated wheel or crank.
	Mechanical Device		A mechanical device such as a float or cam activates the valve. This does not include powered actuators.
	Electric		An electric actuator activates the valve.
	Electro-hydraulic		A servo valve that produces hydraulic control in response to an electrical signal input.
	Electro-pneumatic		A servo valve that produces pneumatic control in response to an electrical signal input.
	Pneumatic		The valve is activated by a pneumatic actuator or cylinder to open and close valve.
	Thermally Actuated		The valve is activated by a change in temperature in the handled media. Typically, temperature and pressure relief occurs once a preset temperature is reached.
	Other		Other unlisted, specialized, or proprietary actuation method.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Material of Construction

	Your choices are...
	Acetal		Acetal polymers are semi-crystalline. They offer excellent inherent lubricity, fatigue resistance, and chemical resistance. Acetal suffers from outgassing problems at elevated temperatures, and is brittle at low temperatures. Glass filled, and added lubrication grades are available, flame-retardant grades are not. Brand names include Celcon® (Hoechst Celanese), Delrin® (DuPont), Thermocomp® (LNP), Ultraform® (BASF), and Acetron® (DSM).
	Aluminum		Aluminum is a bluish silver-white malleable ductile light trivalent metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.
	Brass / Bronze		Brass comes with good strength, excellent high temperature ductility and reasonable cold ductility, good conductivity, excellent corrosion resistance, good bearing properties and low magnetic permeability. Sintered bronze is a porous material, which can be impregnated with oil, graphite or PTFE. Not suitable for heavily loaded applications but useful where lubrication is inconvenient.
	Cast Iron		The term "cast iron" refers not to a single material, but to a family of materials whose major constituent is iron, with important trace amounts of carbon and silicon. Cast irons are natural composite materials whose properties are determined by their microstructures - the stable and metastable phases formed during solidification or subsequent heat treatment. The major microstructural constituents of cast irons are: the chemical and morphological forms taken by carbon, and the continuous metal matrix in which the carbon and/or carbide are dispersed.
	Copper		A common reddish metallic element that is ductile and malleable and is one of the best conductors of heat and electricity.
	CPVC		Chlorinated polyvinyl chloride (CPC) a higher type grade of plastic commonly used for hot / cold water distribution, sprinkler piping, and some chemicals. Suitable for high temperatures.
	Ductile Iron		Ductile iron retains cast iron's machinability and corrosion-resistance, and provides additional strength, toughness, and ductility. Although it’s chemical properties are similar to those of cast iron, ductile iron incorporates significant casting refinements, additional metallurgical processes, and superior quality control.
	Exotic Metal		Exotic metals and alloys have specialized properties. This category includes materials such as Hastelloy®, Monel®, beryllium copper, beryllium nickel, niobium, tantalum, titanium and zirconium.
	Nylon - Polyamide		Thermoplastic resin used for mechanical parts. Can be extracted, cast or injection molded.  The most common commercial grade is Nylon 6/6.  Can to glass filled to further enhance structural impact strength and rigidity.
	PEEK		Polyetheretherketone or Polyketones. PEEK is a semi-crystalline thermoplastic with excellent mechanical properties.
	Polyethylene (PE)		Commodity thermoplastic that is soft, flexible and tough - even at low temperatures - with outstanding electrical properties but poor temperature resistance. It also has very good chemical resistance but is prone to environmental stress cracking; it has poor UV resistance (unless modified) and poor barrier properties, except to water.
	Polypropylene (PP)		Polypropylene is a thermoplastic material exhibiting excellent cold flow, bi-axial strength, and yield elongation properties. It is similar to PVC but can be used in exposed applications because of its resistance to UV, weathering, and ozone.
	PTFE - Teflon®		Polytetrafluoroethylene (PTFE) is an insoluble compound that exhibits a high degree of chemical resistance and a low coefficient of friction. It is sometimes marketed in proprietary classes of materials such as Teflon®, a registered trademark of DuPont Dow Elastomers.
	PVDF		Polyvinylidene fluoride (PVDF) is a melt processable fluoropolymer. It is similar in properties to other fluoropolymer, but has better strength and lower creep than the other members of this family. PVDF has good wear resistance, and excellent chemical resistance. But does not perform well at elevated temperatures. Brand names include: Kynar® (Elf AtoChem).
	PVC		Polyvinyl Chloride (PVC) is a widely used material that has good flexibility, smooth surface, and nontoxic qualities. Some grades are used in food and chemical processes due to the inert nature of PVC. Brand names include: ACP® and Dural® (Alpha Gary), Geon® (Geon), Benvic® (Solvay), Flexalloy® (Teknor Apex).
	Stainless Steel		Stainless steel is chemical and corrosion resistant and can have relatively high-pressure ratings.
	Steel		Steel is a commercial iron that contains carbon in any amount up to about 1.7 percent as an essential alloying constituent. It is malleable when under suitable conditions, and is distinguished from cast iron by its malleability and lower carbon content.
	Other		Other unlisted, specialized, or proprietary material.
