SERIES 730 MASS FLOW CONTROL VALVES
The Series 730 Mass Flow Control Valves were designed by Dr. Jerry Kurz in about 1980 to provide a simple, compact electrically operated, precise metering valve for applications requiring a high flow rate turn-down ratio. The unique Kurz design utilizes a rotor having a helical shape machined into its bottom face, opposite an inlet orifice and an outlet orifice. The diameter, separation and the helical depth were designed to provide a nearly linear flow coefficient (Cv) with angular rotation. A simple high torque gearmotor (24 VDC) was selected for cost and simplicity. Since the Series 730 is a "fail-as-is" design, the motor is only used when changes are required, which greatly extends the motor life. The Series 730 combines the electric drive motor, the valve body, rotor and limit switches into a well-designed, integrated package. The typical turn-down ratio is 50:1, due to the incorporation of a pressure assisted shut-off disk which becomes active near the shut-off position. The Cv range is from 0.05 to 10.0 in three convenient body sizes. The Series 730 is constructed of 316L stainless steel, with Viton O'Rings and an o'ring sealed motor cover. It operates as a two-wire loop-powered device normally powered and controlled by one of the Series 155 Mass Flow Computers and used with a Kurz In-Line Mass Flow Element. The inlet and outlet fittings are Schedule 40 pipe with MNPT end connections or Class 150 flanges. Because of its rotary design, the Series 730 is not as affected by abrupt line pressure changes as are pneumatic control valves

Demand continues to mount for improved comfort conditioning combined with lower operating costs. New architectural designs have created real problems for contractors and engineers to maintain humidity control at reduced loads, and to control load variations. Refrigeration and air conditioning systems are usually designed to provide a given capacity at maximum conditions. These operate with little fluctuation throughout a narrow load range. However, only the larger size machines make any provisions for operation at reduced capacity. In some systems, integral cylinder unloading, the installation of a gas engine drive with variable speed control, or even multiple smaller systems, provide a logical solution.

Superior Design:
Hayward all-plastic diaphragm valves have been specifically designed to perform in the most demanding liquid, gas, and slurry applications in both on/off and modulating service.
Position Indicator:
Hayward's standard highly visible, beacon-type position indicator will always give positive position indication, unlike rising stem indicators that can be inaccurate because of misadjusted stems. Sight panels are made from clear Eastar®.
Diaphragm Saver:
The Diaphragm Saver travel stop is a standard feature on all sizes of Hayward Diaphragm Valves. Its special design prevents overcompression of the diaphragm and prolongs its service life.
No Corrosion Problems:
These valves have no wetted metal components. The valves will never fail because of corrosion and they do not require painting or epoxy coating to stand up to aggressive environments.
True Union Design:
Hayward Diaphragm Valves with socket or threaded connections have a true union design so that they can be removed from the line without having to disconnect piping connections.

Thermostatic expansion valves are designed for a wide range of air conditioning, refrigeration, heat pump and chiller applications.
Our integral valve line includes valves for commercial and refrigeration applications, as well as heat pump and residential applications. The "Take-A-Part Series" valves are the answer to your unique needs, available for almost any type of application, temperature range, or any known refrigerant. We also offer a complete line of specialty valves. Consult us for your specific system requirements.
The Thermo® Expansion Valve is a precision device designed to regulate the rate of refrigerant liquid flow into the evaporator in the exact proportion to the rate of evaporation of the refrigerant liquid in the evaporator. The amount of refrigerant gas leaving the evaporator can be regulated since the Thermo Valve responds to the temperature of the refrigerant gas leaving the evaporator and the pressure in the evaporator. This controlled flow prevents the return of refrigerant liquid to the compressor. The Thermo Expansion Valve controls the flow of gas by maintaining a pre-determined superheat.

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.

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 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”.

The precise regulation of the air flow into sewage basins does not only influence the optimal quality of your cleaning process but furthermore still saves pure money because the energy-intensive compressed air is well applied in optimal quantities.
A too low oxygen supply leads to insufficient pollutant reduction and consequently to a reduced cleaning performance. In the worst case, an infringement of the desired limits occurs.
A too generous ventilation doesn’t bring any higher cleaning performance, but the energy costs for useless compressor performance can impair your installation effectiveness quite considerably.
Deltafit secures optimum oxygen input to your prozess, saves pure energy costs, works also under heaviest conditions for years without any maintenance – and fault-free. The optimally adapted components are prooving their precision and reliability in thousands of industrial installations in the entire process industry.
