1 DIRECTIONAL CONTROL VALVES 2, 3 AND 4WA DIN POPPET SERIES : 2 C E R T I I E D C O M P A N

2 The Elwood line of DIN Poppet Directional Valves is a modern controls concept in water hydraulics a line of 2, 3 and 4way control valves incorporating the following features: Zero Leakage Positive, drop tight sealing is achieved by poppet type plunger assemblies with resilient seating discs, which close against heat treated stainless steel mitered seats. Extended Poppet Seal Life The dynamic seals never cross ports during operation, therefore, cannot extrude into ports. These seals are wear compensating. Minimal Valve Space Requirements Compact subplate mounted design reduces space requirements by as much as 5%. performed from the top side of the valve without removing the valve from the system. The internals are designed eliminating all "press" fitted as well as "selectively" locked parts or assemblies. Cavities conform to international DIN standards and are sleeved to facilitate seal and parts replacement. Easy Valve Maintenance All normal maintenance can be Directional Control unction lexibility Main control valve function can be changed by removing the top plate and relocating the plugs in the pilot fluid passageways. Less Inventory Required Because such parts as poppets, seals, etc., are interchangeable between 2, 3 and 4way valves, spare parts inventory requirements are minimized. Exchanging the poppet assembly replaces all dynamic seals. Built in low Controls Totally independent "meterin" and/or "meterout" flow control from either port is accomplished by simply limiting the poppet stroke by use of the externally accessible stainless steel flow control screw. Maximum Efficiency of luid low The design of the passageways through Elwood Directional Control Valves, results in outstanding valve efficiency and minimum pressure drops, allowing smaller Elwood valve size selection for most applications. Thus, it is smaller in comparison to competitive valves and requires less manifold space. Six Poppet Models Available Designed for dual speed applications. TO TANK Pilot Designed to Suit Application or heavy duty mill type applications, our standard air actuated packed spool pilot valve (Bulletin E82) is furnished. This valve requires no secondary operating media. SIMPLIIED SECTION THROUGH 4WA CONTROL VALVE.

As many as nine (9) positions are available in one valve, though normally, only 4 to 5 positions are used. This flexibility eliminates the need for additional valving and manifold space. Any existing standard 3position Elwood Valve can be converted to provide multiposition valves. This offers considerable versatility in the field, as design requirements change, without requiring manifold or piping changes. Basic valves are interchangeable, therefore spares are minimized. In addition to the illustrated functions, several others are available; contact Elwood. eatures: This example demonstrates how circuit design, manifolding and piping are simplified. This is achieved by eliminating the need for pipedin or manifolded speed and flow control valves. The Elwood Valves have integral externally adjustable flow control screws. HeavyDuty Durable Design Using CorrosionResistant Materials: Seals are selfcompensating. The same piston rings are used throughout. Spool is hydraulicbalanced, assuring uniform wear and eliminates concentricity problems. Designed with nolap fitted parts.

NOTE: If hydraulic fluid contamination is a concern, contact Elwood for information on the incorporation of a pilot filter.

6 Valve Sizing Valve sizing and selection requires consideration in two (2) areas: 1) PIPE VELOCIT & DROP Allowable maximum pipe velocity is based on various system considerations and fluid velocity and resultant pressure drop. Generally, the following flow rates are acceptable parameters for most piping systems: for shorttomedium length runs, 26 feet per second (8 meters per second), and a maximum of 3 feet per second (9 meters per second). for long piping runs, 2 feet per second (6 meters per second). These parameters consider pressure drop. However, to do a complete engineering analysis, one would need to calculate the length of actual pipe runs, factoring in the number of elbows, valves, etc., to determine the system pressure drop. In this case, Cranes Referenceor other reference can be used. 2) DROP THROUGH THE VALVE or correct valve sizing, it is necessary to determine pressure drop through the valve. Due to the fact that not all manufacturers clearly state their valve flow characteristics, it may not seem easy to determine the pressure drop. But, it is simple when the Cv is given. The most effective method for comparing alternative valves is by the Cv factors that valve manufacturers provide for each individual valve. This enables engineers to calculate and compare pressure drops at system design flow rates. This will result in selecting valves with a smaller envelope, but superior internal design and flow characteristics and lower valve and installation costs. 1. P = 2.
