CONTROL VALVES - Series EW Globe Valves The CVS Series EWD, EWS and EWT valve bodies are a single port globe-style body with cage guiding, clamped seat rings and “push-down-to-close” plug action. There are three styles of valves available:
The flow direction for EWD and EWT is normally flow down, and the EWS is normally flow up with the following flow characteristics available: linear, quick opening, and equal percent. The end connections are ANSI Class 300, 600, and 900 Raised Face or Ring Type joint flanges. Buttwelded ends are available in Schedule 40 or 80 for class 300 and 600 and schedule 80 or XXS for class 900. Valve bodies are available in LCC, WCB and 316sst material.

CHEMICAL PUMPS - Series 51 The CVS Controls gas driven Series 51 Injector uses a molded diaphragm to drive a piston through the chevron packing making it a positive displacement pump, capable of discharge pressures up to 6000 PSIG. A pilot valve directs incoming operating gas behind the diaphragm, which causes the diaphragm to stroke forward. The valve shuts off the inlet pressure and opens to expel the spent gas behind the diaphragm and the cycle repeats. A choice of three plunger sizes, and two stroke lengths, allows for a wide range in capacity, from less than one quart to 30 gallons per day. The Micro Valve unit is a miniature valve offering reliability and rugged construction. With an over-centre, snap action-action operator, the unit consists of a three-way, two-position valve. The unit offers sure response, no neutral position and no varying time lag between positions. The unit maintains either position without holding force, and cannot be vibrated or jarred out of position. The Micro Valve Unit negates any requirement for lubrication in the pump cavity, making this unit environmentally friendly. The standard fluid end is ductile iron with stainless steel trim and plunger. All stainless steel is an available option. Applications:

PRESSURE CONTROLLERS CVS Controls offers two types of pressure controllers:
The CVS 4150 and 4160 are pneumatic pressure controllers that utilize a bourdon tube or bellows for sensing vapor, liquid or gas pressure, and differential pressure. The CVS controller can be reconfigured from direct, to reverse acting or vice versa without any additional parts. |
|
The CVS Pressure Controllers offer dependability, toughness, sturdy construction, reliable performance, and accurate service. With regular scheduled maintenance, the pressure controller will provide continuous service for many years.
