Added manual type. New Two types of handle operation methods can be selected. 90° turn type

Multi-turn type

 Enables quick valve open/ close switching operation.

90°

Valve open

650

Valve closed

 The handle will spin loosely at the fully-open and fully-closed positions of the valve. This prevents overtightening.  An indicator enables easy visual check of the open/ closed state of the valve.  The valve opening position can be freely set using a lock nut.

Guide ring Eliminates lateral motion of the poppet which reduces internal leakage.

Piston damper Absorbs piston momentum to minimize impact-induced particle generation.

LVA

Buffer

Diaphragm (PTFE)

Protects diaphragm from deformation and damage due to back pressure.

Special diaphragm construction ensures gentle opening and closing that prevents the formation of micro-bubbles.

Offers quadruple seal construction. Nut lock mechanism—no additional tightening required. High flexural strength. Different tubing sizes can be selected.

Residual liquid is minimized by the tapered shape and integral fitting construction, allowing liquid to flow smoothly, achieving improved flow-through characteristics.

The material and fluid compatibility check list provides reference values as a guide only. Note 1) Since static electricity may be generated, implement suitable countermeasures. Note 2) Use caution as permeation may occur. The permeated fluid may effect the parts of other materials. • Compatibility is indicated for fluid temperatures of 100°C or less. • The material and fluid compatibility check list provides reference values as a guide only, therefore we do not guarantee the application to our product. • The data above is based on the information presented by the material manufacturers. • SMC is not responsible for its accuracy and any damage happened because of this data. • Use a fluid with a viscosity of 300 cp or less. Failure to do so may cause valve closing failure.

Caution

1. Confirm the specifications. Give careful consideration to operating conditions such as the application, fluid and environment, and use within the operating ranges specified in this catalog.

2. Fluids Operate after confirming the compatibility of the product's component materials with fluids, using the check list on page 722. Contact SMC regarding fluids other than those in the check list. Operate within the indicated fluid temperature range.

3. Maintenance space Ensure the necessary space for maintenance and inspections.

4. Fluid pressure range Keep the supplied fluid pressure within the operating pressure range specified in this catalog.

5. Ambient environment Operate within the ambient operating temperature range. After confirming the compatibility of the product's component materials with the ambient environment, operate so that fluid does not adhere to the product's exterior surfaces.

6. Liquid seals When circulating fluid Provide a relief valve in the system so that fluid does not get into the liquid seal circuit.

7. Countermeasures for static electricity Since static electricity may be generated depending on the fluid being used, implement suitable countermeasures.

LVC

1. Preparation before piping Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil and other debris from inside the pipe. Install piping so that it does not apply pulling, pressing, bending or other forces on the valve body.

Operating Environment

Warning 1. Do not use in a location having an explosive atmosphere. 2. Do not use in locations where vibration or impact occurs. 3. Do not use in locations where radiated heat will be received from nearby heat sources. Maintenance

Warning 1. Maintenance should be performed in accordance with the procedures in the operation manual. Incorrect handling can cause damage or malfunction of machinery and equipment, etc.

2. Before removing equipment or compressed air supply/exhaust devices, shut off the air and power supplies, and exhaust compressed air from the system. Further, when restarting equipment after remounting or replacement, first confirm safety and then check the equipment for normal operation. 3. Perform work after removing residual chemicals and carefully replacing them with pure water or air, etc. 4. Do not disassemble the product. Products which have been disassembled cannot be guaranteed. If disassembly is necessary, contact SMC.

Caution 1. Removal of drainage Precautions

Warning 1. Operate within the ranges of the maximum operating pressure and back pressure.

Caution 1. Please note that when the product is shipped from the factory, gases such as N2 and air may leak from the valve at a rate of 1 cm3/min (when pressurized). 2. When operated at a very low flow rate, the product with flow rate adjustment may vibrate, etc. depending on the operating conditions. Therefore, operate only after careful examination of the flow rate, pressure and piping conditions. 3. Water hammering may occur depending on the fluid pressure conditions. In most cases, improvement is possible by adjusting the pilot pressure with a speed controller, etc., but the flow rate, pressure and piping conditions should be reviewed. 4. To adjust the flow rate with flow rate adjustment, open gradually starting from the fully closed condition. Opening is accomplished by turning the adjustment knob counterclockwise. Additionally, do not apply any unreasonable force to the adjustment handle when nearing a fully opened or closed condition. This may result in deformation of the orifice sheet surface or damage to the threaded part of the adjustment handle. The handle is in the fully closed condition when the product is shipped from the factory. 5. After long periods of nonuse, perform a test run before beginning regular operation. 6. Since the product is packaged in a clean room, use sufficient care in handling when opened.
