Ball Valves feature zero leakage design

          Tipvalve supply with the ball valve design features Zero Leakage. The new ball valve represents the next generation in ball valves featuring zero leakage of the body, seat and stem. During development, the ball valve was subjected to extremely rigorous computer-aided analysis, laboratory and field testing. The performance of the ball valves featuring zero leakage is better than any other ball valve on the market.

All-Plastic Ball Valves are designed to stand out in plant

            True Union "Z-Ball" Valves for Sodium Hypochlorite service easy for plant maintenance personnel. Available in PVC for sizes from 1/4"-3/8" and in PVC or CPVC for sizes from 1/2"-6", the valves feature a visibly identifiable black handle that makes them easy to spot and special labeling that identifies their use for Sodium Hypochlorite applications in a plant environment.

Ball Valves offer positive, quarter-turn shutoff

            Multipurpose ball valves mark the continuing expansion of the line of ball valves available. The ball valve offers positive, quarter-turn shutoff for general process and control applications in fluid systems. The new ball valves have main features of SS316 construction, spring-loaded seats, floating ball, low-torque operation and compact design.

Ball Valves have fully machined bore for clog resistance

           NACE-complaint, fire-safe ball valve is suitable for oil field and Petrochem applications and available to manual, electric and pneumatic spring-return or double acting units. New fire-safe F91 stainless steel flanged ball valve adopts a regular-port design to minimize cost and reduce operating torque while offering rugged construction with a solid uni-body and patented pyramidal stem packing. Ideal for applications from the oil field to food processing plants, the ANSI-class 150 valves are fire-safe, comply with the NACE MR0175 standard for corrosion resistance and are certified to API 607-4th edition. The live-loaded pyramidal stem packing system features a patented 45° primary seal with Belleville washers and chevron packing, protecting against wear and stems leaks common with ordinary ball valves. A patented automation pad allows direct mounting of ISO5211-compliant actuators to eliminate the cost and fabrication of special couplings or brackets.

...

Three-Way Ball Valves offer chemical resistance

           New generation of 3-way actuated ball valves such as the Electrically Actuated Ball Valve and the Pneumatically Actuated Ball Valve offer high stability and excellent flow characteristics. These valves incorporate all the inherent advantages which are offered with the new EA 21 electric actuator and PA21 pneumatic actuator.

...

Installation of the ball valves in power plants

             All power plant ball valves are furnished with flow or directional indication ­clearly shown on the valve in the form of an arrow, a label or both. These are critical as the valve must be installed in the proper flow orientation. If installed backwards, for example, the seat would no longer be a sealing member, the load spring would be crushed by the system differential pressure and the valve would fail. Proper clearances must be allowed for lever handles and actuators as misalignment can either cause short stroking or cause the stem side to load, which leads to premature failure.

Flanged Ball Valves feature fire-tested design

            We can supply a kind of flanged ball valves that is available in full port or standard port design. The ball valve body is available in carbon steel or stainless steel with SS316 trim (ball and stem). The flanged ball valve is also Fire-tested to API607 4th Edition & ISO 10497 with TFM seats providing superior high temperature performance and chemical resistance. ISO 5211 direct mounting with adjustable packing is a unique feature. The ball valve can be equipped with a manual handle or with direct mount pneumatic or electric actuators. The direct mount actuators eliminate the valve-actuator mounting kit provides compact assembly to ease installation and eliminates unnecessary height and expense. A full range of accessory items is available including limit switches, solenoid valves, positioners and manual override devices.

Automation of the ball valves in power plants

Ball valves are much easier to automate than multi-turn and rising stem valves partly as operation of the ball valve is a simple 90-degree turn. Duo to the internal flow path through ball valves, most power plant ball valve automation occurs with two position actuators—open and close. Throttling or operation in partially open positions is not recommended for these valves.

...

Multiport Series ball valves

         Multiport Series ball valves feature multidirectional flow combined with shutoff capacity in one valve. Offering 3-way and 4-way flow control, the Multiport Series valves are available in two different body styles including a compact standard port and a block style full port. Valve duplication and the need for an extra shutoff valve are eliminated.

...

Selection of the ball valves in power plants

The port size should be considered to specify power plant ball valves. A reduction in port size causes an increase in system pressure loss through the valve and results in an increase in fluid velocity through the restricted port. Power plant ball valves were originally and primarily designed for vent sand drains applications. As vents and drains normally are used for short durations, the increase in velocity through the ball port does not produce a large wear factor. But the system pressure loss and the velocity also will be continuous in continuous process applications, which can mean premature failure of restricted port valves.
