Designed for controlling very low flow rates of liquids and gases, MFVTM Barstock valves are available in seven conveniently overlapping orifice-needle sizes. Offered in straight (T) and 90 degree (L) flow patterns, the MFVTM Barstock Valve includes a “non-rising stem” design, it’s unique non-rotating needle is cylindrical with a precision ground tapered metering surface. The needle moves in a rectilinear fashion which accounts for its desirable sixteen- turn high resolution attribute. Hysteresis is virtually eliminated due to the needle design and the closely fitting fine thread on its...

MVTTM Metering valves are constructed of PTFE and PCTFE materials. Non-fluid contacting external parts are made of anodized aluminum. Valves are offered in three conveniently overlapping flow ranges. Safety handle prevents over tightening and facilitates fine metered regulation. MVTTM valves are useful in regulating the flow of corrosive gases and liquids. They may be used in pressure or non-critical vacuum service and serve as bubble tight shutoff valves.

PTFE NEEDLE VALVES These compact and reliable PTFE needle valves are designed for laboratory and industrial applications for regulating corrosive gases and liquids or for high purity service. They may also be used as shut off valves. PTFE Needle valve with Aluminum Shell and Glass Nipples Pliant PTFE bodies of the valves are reinforced by structurally rigid metallic shells. Fluids contact only PTFE and PCTFE materials. Shells are made of anodized aluminum or type 316 stainless steel and bushings are made of plated brass or 316 stainless steel. Where externally corrosive conditions exist...

design features ✓ Fluids contact PTFE and PCTFE only. ✓ One PTFE o-ring. ✓ Simplicity, only six components. PTFE needle valves are designed for laboratory and industrial applications for regulating corrosive gases and liquids or for high purity service. They may also be used as shut off valves. Fluids contact only PTFE and PCTFE materials. Valve spindles are made of rigid PCT-FE to minimize the undesirable material “creeping” normally associated with PTFE. PTFE valves are designed for relatively high flow ranges while still performing well in low flow rates. Valves may be used in pressure...

PROPORTIONATING VALVES * Based on 10 psig (690 mbar) differential pressure for sizes 1-4 20 PSIG 1380 mBar for size 5. PSV Proportionating Electromagnetic Valves are designed to respond to variable power inputs to proportionately regulate the flow of liquids and gases. For added safety PSV valves are normally closed (NC) when de-energized. They can also serve as “ON-OFF” valves. For control functions see the PSV-D Driver Module. Flow is controlled by increasing or decreasing the voltage applied to the coil. This causes a magnetic force which raises the core and allows gas to flow. PSV...

Pulse Width Modulated Driver Module Shown with PSV Valve Dimensions Pulse Width Modulated Driver Module Pulse width modulated PSV-D Driver Modules regulate the power supplied to PSV Regulating valves based on a reference signal. Set-point signals, 0-5 Vdc or 4-20 mA, input are employed to control the output pulse width modulated voltage at a fixed frequency (»30KHz) and amplitude. Incoming power to the valve coil is applied and discontinued for predetermined periods of time by a low loss solid state switching element. As incoming power is applied, energy in the inductive coils increases and...

V Valve PSV-D Output vs. Input Control Signal Jumper selectable output power allows a choice of dc voltage range for cooler more efficient operation, as a function of flow rates. Internal resettable fuse protects electronics and rectifier circuits, prevents polarity reversal damage. The maximum output voltage supplied to the PSV Valve can be set or changed in the field to allow for optimal use of the input reference signal to output voltage based on the specific flow rate and operating pressure applied to the valve. POWER INPUT REQUIRED: INPUT SIGNAL: TTL ON/OFF: VALVE OUTPUT POWER: FUSE...
