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.
   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.
   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. 
   Pilot Operated       A pilot valve activates the valve. 
   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.

Primary Material of Construction
   Metals       
   Your choices are...         
   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. 
   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. 
   Copper       A common reddish metallic element that is ductile and malleable and is one of the best conductors of heat and electricity. 
   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. 
   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. 
   Other       Other unlisted, specialized, or proprietary material. 
   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.
   Plastics:      Please consult the manufacturer of the valve for specific properties of the materials used in the valve.
   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). 
   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). 
   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. 
   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. 
   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. 
   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. 
   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). 
   Rubber       Any of several material compositions with properties similar to natural rubber. 
   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.
