APPLICATION:
To control the flow of Water, Air, Gas, Solvents, Vacuum and any other fluids not reactive with construction materials and free of sediment. Buna N seating of the main orifice make the valves ideal for TIGHT SEATING, LOW PRESSURE and LOW FLOW conditions. Valve operates from zero to maximum differential pressure indicated in table. Valve must be mounted in horizontal pipe with solenoid enclosure vertical and on top.
OPERATION:
Valve opens when energized and closes when de-energized. In this direct acting valve the disc holder assembly is lifted from its seat by the plunger.

APPLICATION:
To control the flow of Water, Oil, Air, Gas, Solvents, Brine, Vacuum and any other fluids not reactive with construction materials and free of sediment. Valve operates from zero to maximum differential pressure indicated in table. Valve must be mounted in horizontal pipe with solenoid enclosure vertical and on top.
OPERATION:
Valve opens when energized and closes when de-energized. When the coil is energized the pilot valve opens, relieving the pressure above the piston, which is then lifted from its seat by the plunger. Upon de-energizing the coil, a spring closes the pilot valve and opens a bleed passageway to permit pressure to build above the piston and seat it.

Style 575 Angle Ball Valve
The Dresser® Style 575 Angle Ball Valve provides dual service... as a main-to-service compression end tee connection, and as a shut-off valve.
Constructed of a unique combination of a rugged ductile iron body and a highstrength engineered plastic plug, the "575" valve offers a low torque 90-degree operation with positive, bottle-tight shut-off at pressures up to 125 psi.
Designed for durability under all service conditions, the interface of ductile and engineered plastic components eliminates any possibility of valve freeze-up due to corrosion.
The "575" eliminates the presence of an isolated metallic valve in a plastic service. The ductile material in the valve body is compatible with the cast iron main, so there's no need for anoding and monitoring. Plus, an optional AL-CLAD® Plastisol coating can provide even greater external corrosion protection. The compression end for connecting the service is of a time-proven Dresser design and meets all the requirements of D.O.T. 192.283(b), providing a permanent seal and pull-out resistance greater than the PE tubing in tension.
The "575" is available in inlet sizes 1-1/4" or 1-1/2" MIPT and an outlet size of 1-1/8" OD, but it can be readily adapted to other outlet sizes as required.

General description
Butterfly valves are the most efficient and reliable sealing Isolation valve mechanism under high vacuum working conditions. A vacuum seal provided around the plate periphery in the main body of the valve ensures fail proof working of the valve. For efficient working of the valve it is advised to ensure that the sealing plates are facing atmosphere.
Butterfly Valves are of small in terms of thickness which ensures easy and faster passage for air and gases and are ideally suited for "In-line" isolation purpose. Though the butterfly valve is not intended to be used as an independent valve, it is widely used as a Baffle Valve in union with a chevron baffle at the top of a Diffusion Pump. These Butterfly Valves are offered in stainless steel SS-304 non-magnetic AISI quality high carbon steel chromium plated construction and they can be manually or pneumatically operated as per customer choice.

Weir SPM's Full Bore Unloading Valves provide over-pressure protection for pumps operating under a variety of pressures and flow conditions. The valves are compact, simple to operate, and rely on the system's pressure to open when a preset pressure is exceeded and automatically snaps shut when the pressure drops.
Features/Benefits
The valves are externally adjustable, and unlike shear relief valves which use common nails to trigger the valve, Weir SPM's Full Bore Unloading Valve utilizes nitrogen or rig air (properly filtered) to activate opening and closing. This model is available in 3" and 4" sizes. Operating pressures range from 5,000 psi to 20,000 psi. Standard service and sour gas models are available.
Remote Relief
Utilized together, the Full Bore Unloading Valve and Remote Control Panel increase safety for operators on drilling sites. Weir SPM designed a Remote Control Panel to work in conjunction with Weir SPM's Full Bore Unloading Valve (drilling applications) and the Emergency Backpressure Relief Valve (well service applications). The Remote Control Panel's primary function is to regulate the flow of air or nitrogen to the relief valve from a designated control station, allowing the operator to change the pressure relief settings with the turn of a knob at a safe distance.

SAFETY VALVES
This series of switch valves have been developed due to the safety level that Gas installations with Low, Average and High pressure require. Called SHUT %u2013 OFF, they get operational immediately when a electrical power %u2013 off is detected, making impossible to conect them automatically %u2013 requiring the oversight of a Technician. A review of the Gas System must be done and latter reassemble the valve.
They are made with an iron body with coiled or binded connection of 1" to 3", and pressures from 0 to 5 kg/cm2.

Description:
The Becker Model VRP-B-CH Double-Acting Pilot provides pressure control when utilized with a double-acting piston actuated control valve. The VRP-B-CH measures process sensing pressure and positions the double-acting actuator to maintain the setpoint. The VRP-B-CH Pilot may be utilized for pressure control applications with setpoints ranging from 1.0 (6.9 kPa) to 1300 psig (8964 kPa). Due to its low-bleed characteristics, the VRP-B-CH is typically utilized when bleed gas must be discharged to atmosphere.
