One of the longest-running products in the Plast-O-Matic line has received a facelift! Globe-style air shutoff valves Series EST, ELT & EAT -- which have had fabricated bodies since 1967 -- have been redesigned with machined bodies. By switching to high-volume precision machining, we'll be able to keep the costs for these high performance valves at reasonable levels. To eliminate confusion with parts and replacement seal kits, the valve prefix "E" has been replaced with a "B"; new valves will be designated BST, BLT, BAT, etc.
These direct globe style valves continue to be among the most reliable and versatile thermoplastic valves available. Offered in fail-safe normally-open or normally-closed, double-acting, line pressure to open, and 3-way diverter styles, these heavy-duty valves should be used in lieu of a ball valve or diaphragm valve where the valve absolutely, positively must do as required under virtually any circumstances.

Plast-O-Matic Valves, Inc., announces the addition of a normally-open solenoid valve for applications in which it would be dangerous for valves to close or remain closed in the event of a power failure.
In applications that require continuous flow for cooling or other critical applications, Series EASY-NO remains in the open position when it is de-energized. They also offer energy and cost savings considerations for applications that require a valve to be open most of the time, and only closed for periodic system maintenance or similar needs.

of a new catalog describing Series BSR, a balanced, air-operated shut-off valve.
Series BSR is available in 1/2" and 3/4" NPT sizes in Natural Polypropylene
or PVC with EPDM or Viton® seals. This compact shut-off valve is suitable for applications ranging from full
vacuum to 150 PSI inlet or outlet pressure due to its balanced design. (Vacuum
must be specified). Plast-O-Matic Valves, Inc. has introduced a new thermoplastic
check valve, Series CKS, for maintaining pump prime when the liquid source
is below the elevation of the pump. Designed for potable water and highly corrosive
chemicals, this new valve provides a bubble tight seal to trap liquid in the
pump, preventing loss of prime. Series CKS uses a PFA encapsulated spring and poppet to provide a positive,
repetitive seal. Unlike ball-check designs, this pump prime valve is not dependent
on reverse flow or gravity to seal. This enables the valve to close with less
liquid loss, and provides greater versatility in system design. The pump prime valve is available in PVC, Natural Polypropylene, PVDF and PTFE
in 1½", 2" and 3" pipe sizes. Smaller sizes are also available
in a diaphragm design. The Jacksonville Electric Authority provides electric, water, and sewer utility
services. The city uses sodium hypochlorite in lieu of traditional gas chlorination
to disinfect the water supply.

Plast-O-Matic Valves, Inc. introduced a new air-controlled
pressure regulator, Series PRA, at the 1999 Chem Show, November 16. Designed
for highly corrosive and ultra-pure chemicals, this new regulator uses compressed
air to control pressure with greater accuracy. Pressure regulators provide protection for valuable downstream instruments
and filtration systems by converting fluctuating or excessive inlet pressure
to a preset maximum downstream pressure. The PRA will routinely handle inlet
pressure up to 150 psi and accurately maintain a downstream pressure from 5
to 125 psi. The design of the PRA features two opposing large area frictionless rolling
diaphragms. Process pressure is applied to one of the diaphragms; air pressure
is applied to the other. Because the air pressure can be maintained with more
accuracy than the force provided by a spring, the PRA offers greater sensitivity
and less variance from set pressure than any thermoplastic pressure regulator
previously available. The PRA was demonstrated at the 1999 Chem Show in combination
with Plast-O-Matic's new Stabilizer (patent pending) which
measures downstream liquid pressure to provide even greater sensitivity and
performance. In addition to its enhanced performance Series PRA is the first regulator available
with Plast-O-Matic's patented Series PRA is available in a number of rugged thermoplastics, including Grade
1 Type 1 PVC, Natural Polypropylene, and Kynar® PVDF. Elastomers are Viton®,
EPDM, or Buna-N. Pipe sizes range from 1/4" through 3". For further information, please contact Tech Sales at:
Plast-O-Matic Valves, Inc. has
announced the availability of a new air-piloted, thermoplastic 3-way valve with
position indication/verification. The valve is designed to toggle between two
isolated ports opposite a common port. Unlike many 3-way valves, usage of two
different corrosive or ultrapure liquids through the same valve is feasible, as
the two inlet/outlet ports are not shared.
The valve has two inlets and one outlet. One inlet is normally closed and the
other is normally open. Because this valve uses a "balanced design," meaning
all seal diameters are equal, it can also be used in reverse with one inlet
and two outlets. The "balanced design" also permits a wide range of pressure
ratings (full vacuum to 100 psi) at any port whether inlet or outlet.
A spool-type shaft opens and closes the ports. The valve is designed with the
upper port normally open to the common port, and 40-100 psi air pressure is
applied to the pilot to force the shaft down and open the lower port. When air
is exhausted, an isolated, non-wetted spring returns the shaft to its original
position, closing the bottom port and reopening the top port. The design ensures
that one port closes off before the other opens keeping liquids from the separate
ports from co-mingling.
The valve provides electronic position indication that verifies which port
is open at a given time. When the shaft is in its "normally up" position, a
magnet on the shaft energizes a hermetically-sealed sensor indicating that the
top port is open. The signal is used to light an LED display or electronically
transmit the valve position to a control system. When air pressure forces the
shaft down thus closing the lower port, contact is broken on one sensor and
a second sensor is energized.
This lightweight, compact valve is equipped with stainless steel fasteners.
The ports are standard NPT piping with a 1/8" air port and 1/4" inlets/outlets.
Choices of body materials include PVC, CPVC, polypropylene, and PVDF with Viton®
or EPDM seals. Custom sizes to 3" NPT are also available.
For further information, please contact: Plast-O-Matic Valves, Inc. offers the Series RV, a complete line of
thermoplastic Back Pressure Regulators for corrosive and ultra-pure liquids.
Because of the many functions these valves perform, they are also known as relief
valves, back pressure valves, and bypass relief valves.

The Series RV Back Pressure Regulators are available in a choice of proven designs
for specific uses in a piping system. Designs include angle patterns with a
molded PTFE shaft for smooth operation, and in-line models which feature a rolling
diaphragm that eliminates crystallization problems.
Back Pressure Regulators are usually installed directly in the piping line at
the end of a closed loop to create backpressure in the system. Typically, this
ensures that pressures to branch lines or tools off the main line will always
be in the range of the pre-set pressure. They are also used as relief valves
to protect equipment and systems against dangerous overpressures or sudden pressure
surges.
In pumping applications, Back Pressure Regulators are used as bypass relief
valves to prevent pumps from "dead heading" due to unexpected shut-offs downstream.
They are also ideal for creating backpressure to a pump, to increase pump efficiency
and smooth out turbulence.
Back Pressure Regulators are available in pipe sizes from 1/4" - 3" with various
body materials including Grade 1, Type 1 PVC, Polypropylene, Corzan® (CPVC),
Kynar® (PVDF) and PTFE. Seal materials are Buna-N, Viton®, EPDM or PTFE.
Flow rates range from 2 to 200 GPM and set pressures from 5 to 150 PSI. The
valves can be factory modified for special applications.
