The fine threads of the needle valve permit excellent adjustment for precise control of flow. The flow is restricted in both directions and is adjustable from 0 to the equivalent flow of a 0.025" diameter orifice. The 7-turn adjustment needle valves are available in two models, the standard model and the fine adjustment model. The standard adjustment model has a pin angle of 6° with 10-64 threads; the fine adjustment model has a pin angle of 4° with 10-80 threads.

The miniature Preset Flow Control is ideal for many applications involving pneumatic systems, including the control of cylinder speed.
The operation of the flow control is based on the movement of a small disc. The flat surface on one side of the orificed disc seals and permits flow through the orifice. The amount of flow permitted in the reverse direction is determined by the orifice size. In the forward direction full flow is permitted. The flow controls design allows a maximum supply pressure of 75 PSI with a minimum cracking pressure of less than 10” H2O. Orifice sizes are available from .004” to .040”.

Two Proportional Flow Control Rates with One Valve: Hayward ProFile2 corrosion resistant, proportional control ball valves provide two linear flow curves; one for fast opening and one for slow opening. The percentage of flow through the valves with either flow curve is equal to the degree of opening. As the valves are opened or closed, the flow varies in direct proportion to the valve opening. This permits predictable, accurate control of the downstream flow rate with a 1/4 turn valve.
Unique Design "Characterized" Ball: These valves utilize a unique, patented ball with a special "characterized" opening that results in the linear flow rate change. Valves are shipped with the ball installed so that the smaller opening enters the flow first, creating the slow open rate. To switch to the fast opening rate, simply reverse the ball in the valve. With the larger opening first, the flow starts fast with slower, more controlled changes as the ball is turned to "full open".
Perfect With Positioners: Hayward ProFile2 Proportional Control True Union Ball Valves can be supplied with optional electric or pneumatic actuators with positioners for automated modulating service applications.
Never a Problem with Corrosion: Because of their all plastic construction, Hayward ProFile2 ball valves will never rust or corrode. They can survive corrosive environments and harsh weather conditions without the need for painting or expensive epoxy coatings.

Flow Patterns:
Hayward Manual Three-Way Ball Valves come standard with a two port "TW" ball allowing for three flow configurations within 180 degrees of rotation. With the bottom port as the inlet, the flow can be directed out the left port, out the right port or shut off. Hayward Actuated Three-Way Ball Valves come standard with a three port "NT" ball allowing for two flow configurations within 90 degrees of rotation. With the bottom port as the inlet, the flow can be directed out the left port or out the right port, there is no shut off position. A "TW" ball, used with with the proper electric actuator, adds what is typically called a "center off position" to the "NT" flow pattern of actuated valves. An optional "TP" ball, used with either manual or actuated valves, allows flow through all ports at the same time or flow shutoff.
True Union Design:
This makes these valves very easy to maintain by allowing for easy removal from a piping system without breaking down the piping connections. Just unscrew the three assembly nuts and lift the valve body out of the line.
Easy to Actuate:
A manual valve can be easily automated. Just remove the handle and install the optional actuator mounting kit. The mounting saddle is integrally molded into the valve body. For rock-solid actuator mounting, the valve incorporates a unique design whereby the mounting bracket mounts directly to the valve body. This assures proper alignment of the actuator to the valve without creating any damaging side loads to cause premature stem seal failure.
No Metal, No Corrosion:
Hayward all plastic three-way valves contain no metal parts. The valves will never fail because of corrosion and they do not require painting or epoxy coating to stand up to aggressive environments.

Rugged, Compact Design:
Hayward's rugged, low cost QIC2 all plastic PVC ball valves incorporate many design features found only on higher cost ball valves. Features such as PTFE seats, full porting and a 150 PSI pressure rating are all standard on every size of QIC2 ball valves.
Cost Sensitive Applications:
The QIC2 ball valve is perfect for OEM and other applications that require a reliable ball valve at an economical price. The QIC2 valve has been designed and tested to make certain it will perform year in and year out in the most demanding applications without leakage or failure. The internal components of the QIC2 ball valve are completely encapsulated inside the one piece valve body which means that the valve never requires adjustment. The QIC2 valve is ready to be put into service right out of the box.
Lightweight and Compact:
QIC2 lowcost ball valves are designed to fit into spaces too small for other valves. They are about 1/3 the overall size of a true union ball valve and they weigh an average of 50% less. This makes them ideal for skid mounted and other applications where space and weight are critical considerations.
Can't Rust, Won't Corrode:
Their all plastic construction means that they will never fail, stick, or jam because of rusted or corroded parts. And they'll work in places and environments where metal valves must be painted or coated just to survive.

Remote Control Valve:
Hayward's Pneumatically Actuated Diaphragm Valves are designed for the reliable, remote control of liquids in piping systems. They are suitable for both clean and slurry type fluids at pressures up to 150 PSI.
Position Indicator:
You never have to guess if a Hayward Diaphragm Valve is in the open or closed position. A visual position indicator comes standard with every valve.
Powerful Actuator:
The actuator used to operate the valve, while lightweight and compact, is still powerful enough to open and close the valve at all internal pressures up to the full rated pressure of the valve,150 PSI.
No Corrosion Problems:
Hayward's Diaphragm Valves stand up to the most aggressive fluids and they will never rust, corrode or contaminate the process fluid. Even the actuator housing is plastic and requires no failure prone coating or painting.
Modular Options:
Several modular design options are available. This concept is very cost effective because the actuator can be configured exactly for a specific application using only the options required. You never have to pay for options you do not need.

The Becker Model VRP Double-Acting Pilot provides pressure control when utilized with a double-acting piston actuated control valve. The Model VRP Valve Regulator Pilot is the “original” VRP-Pilot and is often referred to as the “VRP Classic.” The VRP measures process sensing pressure and positions the double-acting actuator to maintain the setpoint. The VRP Pilot may be utilized for pressure control applications with setpoints ranging from 1.0 psig (6.9 kPa) to 1300 psig (8964 kPa). The VRP is typically utilized when Bleed to Pressure System (BPS™) may be used to completely eliminate atmospheric bleed emissions. The VRP Classic maintains the simplicity of the original VRP concept with “standard” setpoint accuracy and performance. For higher level of performance and accuracy, the Model VRP-CH Valve Regulator Pilot should be utilized. The VRP Classic is utilized primarily by long-term customers that have a large installed base of the original VRP Pilots.
