LARGE SIZE/HIGH PRESSURE AXIAL FLOW VALVES FOR PRESSURE PROTECTION

Petrol Valves has recently delivered 36” Class 1500 axial flow valves specifically developed for HIPPS pressure protection systems. The valves have been designed to achieve the following: minimum pressure drop, low operating time, long life and tight shut-off sealing capability, and low maintenance / high reliability. This article will review some of the main design considerations for valves for HIPPS application.Axial flow valves are often used in High Integrity Pressure Protection Systems (HIPPS) and present peculiar design features to suit HIPPS requirements: short stroke, pressure balanced disc and low internal mass to allow the use of compact actuators with fast response times.

STAINLESS STEEL 3-WAY BUTTERFLY VALVES

Valtorc International is proud to present the first-ever 316 stainless steel 3-way butterfly valve assembly which is fabricated in its USA facility. 3-Way automated butterfly valve is available with pneumatic or electric actuation.

High performance 316 Stainless Steel T-Linkage assembly, all 316 body materials, automated with pneumatic or electric actuation. Complete USA fabrication and tested in our USA fabrication facility.
Actuated 3-way butterfly valves are available from sizes 2″ to 24″ with stainless steel trim. Actuation type is either non-spring return, spring return or double-acting – electric or pneumatic actuation can be applied. Optional (0-10VDC) actuator control signal is available upon request.

Industrial grade 3-way butterfly valve systems are of special construction for storm water runoff. Standard construction for the valve package. EPDM seats and stem with available stainless steel disc. Electric actuation (via the EL-700 electric actuator) comes in various power supplies that include 12VDC, 24VDC, 24VAC, 120VAC, 240VAC and various others. Double D shaft connection for valves 2″ – 30″ in size allows for easy mounting of handles, gearbox operator or actuators. Mounting conforms to ISO 5211 for actuation mounting.

CONTROL AIR ANNOUNCE NEW PRECISION VACUUM REGULATOR

Control Air Inc., a manufacturer of precision pneumatic and electro-pneumatic control products, announced the introduction of the new Type 480V Precision Vacuum Regulator. It is the first vacuum regulator offering from Control Air. The Type 480V Precision Vacuum Regulator provides precise control up to full vacuum. The unit is designed with a push-type locking knob which allows for smooth output adjustment and the ability to lock in your set point to avoid unintentional adjustments.

The Type 480V senses output pressure deviations to within 1/2″ water column pressure. Regulating range is from 0 to 30 in. Hg (-100 to -1.3 kPa). The unit is small in size and lightweight, less than 1 lb. The standard bracket and integral panel nut allows for versatile installation options. A soft valve seat design provides tight shut-off and eliminates leakage in steady-state operation. The Type 480V is ideal for any process requiring precise regulation of vacuum pressure. It is suitable for a wide range of applications which include Semiconductor Manufacturing, Medical OEM, Mass Spectrometry, Pick & Place, and Leak Testing.
