Our goal is to provide the highest quality feature enhanced portfolio to the actuation segment of the process industry.We are pleased to introduce our new Series of High Flow direct mount NAMUR solenoid valves for the Process and Industrial markets. The High Flow Series complements our highly successful specification grade 7300 Series product line. The High Flow product line provides new, cost effective solutions for general purpose customer application needs.Attachments and EnclosuresI Catalog BrochureII List Price SheetIII Installation, Operation andMaintenanceInstructionsIV Competitive FeatureComparisonV CompetitiveCross-Reference ValveListing PRODUCT FEATURESThe High Flow Series is a NAMUR interfaceinternal pilot spool valve for direct mounting toactuators. The NAMUR mount spool valve isavailable for either 3/2 normally closed valveor 5/2 four-way functionality.The axial valve construction allowsa low profile or in-line operatororientation with valve body valve style.The portfolio consists of 1/4” ported single and dual solenoid valves (Cv = 1.2) and a larger high flow 1/2” ported valve (Cv = 3.0) meeting a wide variety of application requirements. (Reference catalog pages and construction reference drawings)The valve body is a hard anodized aluminum. The standard pressure vessel end cap is made of an engineered thermoplastic.The primary valve characteristic is a patented “swimming” o-ring sealing system that increases sealing force as pressure increases thereby minimizing stiction potential at lower pressures. The valve series incorporates numerous other benefits including: •Utilizing a combined pneumatic and spring return for standard fail-safe operation in case of power failure.•The valves are equipped with a standard locking manual override.•The valve uses a “bug screen” nut exhausting the pilot section of the valve to atmosphere for safe outdoor service.•Mounting plates are available for use with the hazardous coils.The spool valve design uses a low power coil for reduced energy consumption and computer base control. DIN, conduit and hazardous coils complete the electrical portfolio.Global Marketing Update No. 134, June 14, 2007 __________________________________________________________________________________________________________________________________ OPERATION FUNCTIONALITY3/2 Single Solenoid (4 ported, 2 position)NAMUR valve, solenoid operated, for 3-way normally closed operation. In case of an electrical or air failure, valve returns to a fail-safe position through pneumatic and assisted spring return.5/2 Single Solenoid (5 ported, 2 position)NAMUR valve solenoid operated, for 4-way, 2 position operation. In case of an electrical or air failure, valve returns to a fail-safe position through pneumatic and assisted spring return.5/2 Dual Solenoid (5 ported, 2 position)NAMUR valve used for 4-way, 2-position operation. In case of an electrical or air failure, valve “fails as is”. Therefore, valve remains in last position upon failure and will not return to a predetermined position.5/3 Dual Solenoid, Center Position Closed (5 ported, 2 position)NAMUR valve used for 4-way, 2-position operation. In case of an electrical or air failure, the spool returns to the center position thereby removing pressure to the cylinder ports.TECHNICAL PRODUCT CHARACTERISTICSThe new line of valve actuation products offer many features and benefits as follows:Modular construction – Facilitates use of various body configurations and coil options.Mounting Configurations - Direct mount NAMUR pattern with axial operator orientation for single and dual solenoid models for low profile mounting requirements.Manual Override – Standard on all models for manual valve operation during start-up and diagnostic procedures.7mm (1.2Cv ) and 12mm (3.0 Cv) orifice sizes – Multiple sizes to meet various application demands to ensure the solenoid valve is properly sized.Body Materials - Lightweight anodized aluminum.Spool Design – Stainless steel with NBR sealing materials.Exhaust Pilot Cap– Protected pilot sleeve exhaust using “Bug Screen” nut.

Why did we introduce the High Flow NAMUR Series valve product line?The principle reason for introducing the valve line is to meet increasing market demands for smaller, cost effective valve models for the process valve actuation markets. The Parker 7300 Series valve line offers a high-end specification grade product in multiple bodymaterials to meet general purpose ordinary requirements to the most stringent application requirements. Also, the 2340 series of aluminum body valves lacked a suitable hazardous coil limiting application potentials.The new product line overcomes the 2340 series deficiencies at a most competitive price for general purpose application requirements. The portfolio includes expanded models with higher flow factors for larger actuator designs. The new line includes a 1/2” namur valve to accommodate the trend toward larger actuators and higher flows.Finally, we’re continuing our strategic thrust in the process markets with a new product offering and responding to competitive product positions.Q? Will the High Flow Series product line replace the 2340 Series and 3300 Series valves?In a word, yes. First, since the introduction of the 2340 series and 3300 series valves(dating back to the late ‘90’s), many changes have taken place in the market. The general purpose ordinary location market generally does not require the high technical or safety standards found in these product lines. Due to deficiencies in the former product lines, specifically the lack of a hazardous coil, we were not able to meet the availability and price competitiveness. The current product lines are focused toward higher technicalrequirements resulting in low-volume market segments and overlap price-wise with the 7300 Series valve lines. To reduce complexity and offer a simplified, cost-effective processactuation valve line, the 2340 catalog portfolio will (eventually) be phased-out.Q? Describe the comparison to the 7300 product line.The High Flow Series offers similar product features and benefits compared to the 7300 Series, in particular:• Total modularity.•Interchangeable electrical parts.•Unique spool designs to eliminate risk of sticking.•High quality in proven valve designs.•Standard manual override.The distinctive features of the High Flow Series compared to the 7300 Series include:• Smaller physical size.•More cost effective compared to 7300 with manual override (for certain type application needs).Q? Where must the 7300 series valves be used versus the new line?The 7300 series contains features, multiple operator configurations and electrical coilsappropriate for more demanding critical applications including:•Higher flows appropriate for higher actuator torque specifications.•Intrinsically Safe (IS) and ultra low power environmental conditions.•Manual reset options used as a safety device on solenoid valves to prevent process resumption without manually resetting each valve.•Low temperatures application demands of –40°F/C.•Field convertible manual overrides including locking and momentary requirements. Q? Will a conversion plate eventually become available?The product line contains individual 3-way and 4-way valve configuration. When utilizing a DIN coil, this method provides the most cost-effective, competitive solution. Granted, whilea conversion plate offers the benefit of using one style valve, it also adds significant andunnecessary costs. Since the valve is focused and priced to pursue higher volumerequirements, the valve functionality will be known.。

电磁阀和液压阀
电磁阀和液压阀电磁阀和液压阀作业⼀、电磁阀电磁阀的“通”和“位”“通”和“位”是换向阀的重要概念。
不同的“通”和“位”构成了不同类型的换向阀。
通常所说的“⼆位阀”、“三位阀”是指换向阀的阀芯有两个或三个不同的⼯作位置。
所谓“⼆通阀”、“三通阀”、“四通阀”是指换向阀的阀体上有两个、三个、四个各不相通且可与系统中不同油管相连的油道接⼝，不同油道之间只能通过阀芯移位时阀⼝的开关来沟通。

7V系列电磁阀安装使用注意事项
1、拿取电磁阀时切勿将其摔、掉落，以免造成电磁阀损坏；
2、因电磁先导阀为精密元件故安装调试电磁阀时，切勿让外力碰、撞先导阀，以免因此造
成电磁阀损坏，图文介绍常见的不良问题：
a.电磁阀单个或多个安装时，外置线强行拉扯导致端子壳坏掉（如下图）。
(1) (2)
(3) (4)
b.在安装接头时阀体较小，先导阀体承受大拇指外力影响导致损坏（如下图）。
(1) (2)
3、使用时请勿随意拆解电磁阀，如因意外引起先导阀螺丝(M1.6×14)松动，请用
0.1~0.15N.m力矩将其拧紧；
4、关于手动操作：
a、手动操作时，请先确认无危险后方可让连接装置进行作动；
b、非锁定推压式使用方法：沿箭头方向向下推压
c、旋具按下回转锁定式使用方法：按下后按箭头方向旋转，若不旋转，则与非锁定推
压式的使用方法相同。
d、手动按下回转锁定式使用方法：压下后沿箭头方向旋转，如不旋转，则与非锁定推
压式的使用方法相同。
