The rugged, self-cleaning elastomer sleeve isolates all mechanical pars of the mechanism, so the break away torque remains constant.
Series 5300 Pinch Control Valve: Red Valve Company has developed a new open frame control pinch valve, the Series 5300. The Series 5300 valve features many of the same advantages of the Series 5200 line of control pinch valves, in a light-weight, low-cost open frame design. The open frame design is possible because the sleeve is the only wetted part of the pinch valve, protecting the operating mechanism and frame from corrosive or abrasive attack from the line process. A heavy-duty, rugged pinch mechanism pinches the sleeve, resulting in accurate flow control. The Series 5300 has no packing to maintain or seats to wear, and is well suited for handling corrosives, powders, and slurries.
Series 5200 Pneumatic Control Pinch Valve: The Red Valve Series 5200 Control Valve design offers maximum durability with precise control and virtually eliminates maintenance. The Series 5200 valve is designed in sizes 1” to 4”. A heavy duty, rugged pinch mechanism positions the sleeve, resulting in accurate flow control. The valve has no packing to maintain or seats to wear, and the need for expensive body alloys is eliminated.
Series 5200 Diaphram Actuated Control Pinch Valve: In smaller sizes, the Series 5200 is available with a diaphragm actuator. The quick-response and low-hysteresis of a diaphragm actuator allows the 5200 to react quickly to input signals. This gives the 5200 Diaphragm great accuracy and repeatability on small-diameter slurry lines.
Series 5200E Control Pinch Valve: The Series 5200E electrically actuated control valve is a reliable, maintenance-free, cost-effective valve, designed for tough slurry and abrasive applications.

The rugged, self-cleaning elastomer sleeve isolates all mechanical parts of the valve, so the breakaway torque remains constant.
Series 5200D Control Pinch Valve: Red Valve's Series 5200 D-Port control valve design results in an economical control valve choice. When fully open, the D-Port has 95% of the flow of a full-ported valve. Flow control begins immediately, providing a linear flow characteristic. The D-Port configuration employs a single actuator which closes from the top. This design shortens the actuator stroke, which in turn reduces operating costs. An external stroke adjustment is provided. The rugged elastomer sleeve is self-cleaning, with no packing to maintain, and provides accurate, repeatable control. The Series 5200 D-Port control valve can be furnished with a standard, double wall, or cone or sleeve design.
Series RSR Pressure Relief Pinch Control Valve: The Red Valve Series RSR Pressure Relief Valve is designed specifically for slurry applications. It is a reliable relief valve available for slurry service, venting surge pressures in the system, or to maintain system pressure. The valve operates very simply – making use of a spring loaded cylinder, which keeps a rugged reinforced rubber pinch valve sleeve pinched closed. As process pressure builds up and exceeds the tension set by the spring, the valve opens. The greater the pressure build–up, the more the valve opens. Since the sleeve isolates the process from the pinch mechanism, corrosion, bridging, plugging, and valve freezing are eliminated.
Hartman Sleeve Valve: Hartman Sleeve Valves achieve superior control while dissipating pressure energy by accelerating fluid through radial nozzles arranged in a properitary pattern.

Air Operated Pinch Valve Type A: Air Actuated Pinch Valves offer a cost-effective solution to flow control problems. The secret is in the rubber sleeve - the valve's only wetted part. Actuation of the valve, the pinching action, is accomplished by air or hydraulic pressure placed directly on the elastomer sleeve. The valve body acts as a built-in actuator, eliminating costly hydraulic, pneumatic, or electric operators. The sleeve's flexibility allows the valve to close droptight around entrapped solids. In general, 25 psi over line pressure is required for full closure of air actuated pinch valves.
