A3000 Photohelic® Switch/Gages for Pressure Measurement up to 25 psig

Photohelic® Switch/Gages function as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelic® gage design. The Photohelic® switch/gage measures and controls positive, negative or differential pressures of air and compatible gases. Standard models are rated to 25 psig (1.7 bar) with options to 35 (2.4) or 80 (5.5 bar) psig. Two phototransistor actuated, DPDT relays are included for low/high limit control. Easy to adjust set point indicators are controlled by knobs located on the gage face. Individual set point deadband is one pointer width - less than 1% of full scale. Set points can be interlocked to provide variable deadband - ideal for control of fans, dampers, etc. Gage reading is continuous and unaffected by switch operation, even during loss of electrical power. Choose from full scale pressure ranges from a low 0-.25 in (0-6 mm) w.c. up to 30 psi (21 bar). NIST CALIBRATION available in Product Configurator.

Brass Flap Check Valve - Prevents Backflow & Reduces Pressure Loss

Series BFC Brass Flap Check Valve is an economical check valve for both commercial and industrial application. Quality brass body and stem construction allow for long service life and reliability. Ideal where backflow could potentially cause damage to equipment by yielding reverse flow. Pressure in the line moves the flap off of the seat, opening the valve. When the inlet flow comes to a halt, back pressure moves the flap back onto the seat, stopping the flow. Designed to provide excellent flow characteristics with minimal turbulence and pressure loss while maintaining its ability to prevent backflow.

CHEMICAL TUBING FEP Formulation Imperial Diameters

FEP tubing is very similar to PFA tubing in flexibility and appearance. The major difference is the service temperature range for FEP: -73 to 204°C (-100 to 400°F). Specifications Hardness, Shore D: 56 Specific Gravity: 2.15 Tensile Strength: 3400 psi Elongation at Break: 325% Brittle Temperature: <-170°C (-275°F) Service Temperature: -73 to 204°C (-100 to 400°F)

Pressure Snubbers to Protect Against Pressure Surges

PRESSURE SNUBBER - for dampening and filtering. The snubber has a porous metal disc available in three standard grades of porosity. Due to the large filter surface the snubber has less tendency to clog than orifice type devices. The housing is 303SS and the filter disc is 316SS with a maximum PSI rating of 10 000 at 25°C. (PS-8 series 5000 PSI) Please note that the finish of pressure snubbers may vary. The flat surfaces on snubbers you receive may have a smooth and machined appearance or they may have a textured, shot-peened appearance. These are merely cosmetic differences that do not affect the functionality and performance of the product.
