Data Sheet MOUTHSHUTTER (TWO-WAY SHUT OFF) PNEUMATIC SLIDING-TYPE™ VALVES Series 4250, 4220, 4260, 4200 Flow Bores 4.8mm, 9.5mm, 15.9mm, 22.2mm Product Description The Mouthshutter (Two-Way Shutoff) Pneumatic Sliding-Type series Directional Control valves are available in several flow bore sizes to accommodate most respiratory circuit requirements for low dead space and low resistance to flow. Pneumatically sliding the piston from one end to the other of the valve redirects the circuit flow path from the common port either straight through to the outlet port or to an occlusion of the flow path. These valves are designed to be pneumatically activated with the Hans Rudolph 4285 Series Controller. The controller uses 50psi drive pressure to activate the piston from one position to the next. The pressure is maintained at the valve only for the time required to move the piston. The valve housing is transparent so the flow path through the piston is easily visible. There are two port adapters that thread directly into the valve housing that can be changed to other available sizes. Each series of valves has three or four standard options for port sizes. Custom port sizes can be provided upon request. Product Features • Four different valve flow bores to cover wide range of applications • Low resistance to flow, no obstructions in valve flow bore • Low dead space volume, design optimized • Transparent main housing for visibility of piston position • ain housing threaded ports are all the same thread for interchangeability of the M port adapters • Common port or housing includes a sampling hose barb • 22mm & 15mm medical tapered ports meet ISO 5356-1:2015 • The three larger flow bore series have a Mounting Rod • O-rings utilized for sealing • Valves are 100% leak tested • Additional sampling ports and couplers available • Connectors in standard and custom types available in Medical tapered, O-ring slip fit, Shaped series and Coupler Lock-Ring Assembles • Pneumatic controller for one or two Slide-Valves General Information Intended Use Mouthshutter (Two-Way Shutoff) Pneumatic Sliding-Type Directional Control Valves are designed for use as an airway occulsion valve typically required in body plethysmography in a pulmonary function lab. These valves can be assembled with two-way non-rebreathing valves and or pneumotachometers to provide additional functions as required by the application. This series of valves are designed in a two-way shutoff configuration with one common port and one outlet port. Pneumatic valve control is accomplished with a pneumatic controller to position the piston from one position to the next. These valves are classified as reusable and can be high level disinfected. These valves are supplied clean, non-sterile. Typical applications are pulmonary function testing and respiratory research. These valves are not intended for use in any critical care or life support applications such as a ventilator circuit or anesthesia. Rebreathing Volume Dead Space Includes the internal air volume of the common port adapter and the flow bore through the main housing and piston. Estimation of the dead space for each valve series with each valve common port adapter combination is listed in the Physical Characteristics section of this data sheet. Cleaning and Disinfection • These products are packaged clean, non-sterile • For cleaning and disinfection care refer to our Instructions for Use 691201 Cautions 1. Federal law restricts this device to sale by or on the order of a physician. 2. Maximum 50 psi drive pressure for value piston actuation. Consult Hans Rudolph for control applications that do not incorporate our 4285 Controller. 3. Do not use these valves in any life support system such as a ventilator or anesthesia circuit. 4. Do not ethylene oxide, steam sterilize or pasteurize these valves.
